Part 2

"I thought so," he said. "I hoped so. It seemed to me that the precautions I had taken placed us absolutely outside the zone of danger. As the years have passed away, and you have grown more and more careless until one were inclined to laugh at your own fears, to wake up, as I did an hour ago, to the knowledge that the danger is not only threatening, but actually here----"

"Here!" Cotter cried, his voice rising almost to a scream. "You don't mean it, sir. You are joking. You are playing with your old servant. The mere thought of it brings my heart into my mouth and sets me trembling."

By way of reply Flower proceeded to explain the strange occurrence in the conservatory. When he had finished he laid the piece of silken thread upon the table. Its effect upon Cotter was extraordinary. He tore frantically at his scanty grey hair. Then he laid his head upon the table and burst into a flood of senile tears.

"What is the good of going on like that?" Flower said irritably. "There is work to be done and no time to be lost. I know you are bold enough in the ordinary course of things, and can face danger when you see it. The peculiar horror of this thing is its absolute invisibility. But we shall have to grapple with it. We shall have to fight it out alone. But, first of all, there is something to be done which admits of no delay. I sent into Oldborough for a doctor, and who should turn up but that very man Mercer, who nearly succeeded in bringing a hornet's nest about our ears over that affair of the _Guelder Rose_. I should never have remembered the fellow if he had not foolishly let out that he was a ship's doctor, and naturally I kept my information to myself.

"You know what I want done? That man is poor and struggling. He has to be crushed. Find out all about him. Find out what he owes and where he owes it. Then you can come to me and I will tell you how to act. No half measures, mind. Mercer is to be driven out of the country, and he is not to return."

Cotter grinned approvingly. This was a commission after his own heart. But from time to time his eyes wandered to that innocent looking piece of string upon the table, and his face glistened with a greasy perspiration.

"And about that, sir?" he asked with a shudder.

"That will have to keep for the moment. I want you to go to the post-office and fetch the letters. I am expecting something very important from our agents in Borneo, and you will probably find a registered letter from them. It relates to that matter of Chutney & Co. It will be written in a cypher which you understand as well as I do. You had better open it and read it, in case there may be urgent reasons for cabling a reply at once. As soon as this business is done with and out of the way, Cotter, the better I shall be pleased. It is a bit dangerous even for us. Of course, we can trust Slater, who does everything himself and always uses the cypher which I defy even Scotland Yard to unravel. Still, as I said before, the work is dangerous, and I will never take on a scheme like that again. You had better use one of the cars as far as the post-office to save time."

"I shall be glad to," Cotter muttered. "I should never dare to walk down to the village in the dark after seeing this infernal piece of string. The mere sight of it makes me shiver."

Cotter muttered himself out of the room and Flower was left to his own thoughts. He sat for half an hour or more till the door opened and Cotter staggered into the room. He held in a shaking hand an envelope marked with the blue lines which usually accompany registered letters. "Look at it," he mumbled. "That came straight from Borneo, written by Slater himself, sealed with his own private seal, and every line of it in cypher. I should be prepared to swear that no one but Slater had touched it. And then when I come to open the envelope, what do I find inside? Why, this! This! This!"

With quivering fingers Cotter drew the letter from the envelope and unfolded the doubled-up page. From the middle of it dropped a smooth silken object which fell upon the table. It was another mysterious five-knotted string.

*CHAPTER IV*

*IN THE WOOD*

Master and man stared at each other blankly. Unmistakable fear was visible in the eyes of both. And yet those two standing there face to face were supposed not to know what fear meant. There was something ridiculous in the idea that an innocent looking piece of string should produce so remarkable an effect. It was long before either spoke. Flower paced up and down the room, his thin lips pressed together, his face lined with anxiety.

"I cannot understand it at all," he said at length. "I thought this danger was ended."

"But there it is," Cotter replied. "If these people were not so clever I should not mind. And the more you think of it, sir, the worse it becomes. Fancy that message finding its way into Slater's letter. The thing seems almost impossible; like one of those weird conjuring tricks we used to see in India. And Slater is a cautious man who runs no risks. He wrote that letter in his own hand. He posted it himself, you may be sure. And from the time that it dropped into the letter-box to the time it reached my hand, nobody but the postal officials touched it. Yet there it is, sir, there it is staring us in the face, more deadly and more dangerous than a weapon in the hands of a lunatic. Still, we have got our warning, and I dare say we shall have time----"

"But shall we?" Flower said impatiently. "Don't be too sure. You have forgotten what I told you about Miss Galloway and the mysterious hand that was trying to force a way into the conservatory. She doesn't know the significance of that attempt, and there is no reason why she should. But we know, Cotter. We know only too well that the danger is not only coming, but that it is here. Unless I am mistaken it threatens us from more quarters than one. But it is folly to discuss this matter when there is so much to be done! I have friends coming to dinner, curse it, and more are expected later in the evening. I must leave this matter to you and you must do the best you can. Prowl about the place, Cotter. Keep your eyes open. Pry into dark corners. See that all the windows are closed. Perhaps you might also explain something of this to the keeper, and ask him to chain one or two dogs up near the house. They may be useful."

Cotter acquiesced, but it was evident from the expression of his face that he did not feel in the least impressed by his employer's suggestions. This dark, intangible danger was not to be warded off by commonplace precautions. For some time after Cotter had gone Flower sat at his table thinking deeply. The longer he pondered the matter, the more inexplicable it became. Beatrice's discovery was grave enough, but this business of the registered letter was a thousand times worse. Nobody appreciated daring, audacity, and courage more than Flower. He knew what a strong asset they were in success in life; indeed, they had made him what he was. But this cleverness and audacity were far beyond his own. He took up the silken string and twisted it nervously in his fingers.

"What is it?" he murmured. "How is the thing done? And why do they send on this warning? What a horrible business it all is! To be hale and hearty one minute and be found dead the next, and not a single doctor in the world able to say how the end is brought about! And when you tackle those fellows there is no safety. Why shouldn't they bribe some dissolute scamp of an Englishman to do the same thing after showing him the way. There are dozens of men in the city of London who would put an end to me with pleasure, if they could only do so with impunity."

Flower rose wearily and left the library. He was tired of his own thoughts and for once had a longing for human society. As he went along the corridor leading to the hall, one of the maids passed him with a white face and every sign of fear and distress. With a feeling of irritation he stopped the girl and inquired what was the matter.

"What has come to the place?" he muttered. "And what have you been crying about? Aren't you Miss Galloway's maid?"

"Yes, sir," the girl murmured. "It is nothing, sir. As I was coming from the wood at the back of the house, on my way home from the village, I had a fright. I told Miss Galloway about it and she told me not to be silly. I dare say if I had looked closer, I should have found that----"

The girl's voice trailed off incoherently and Flower suffered her to go away. It was not for him to trouble himself over the fears and fancies of his servants, and at any other time he would have shown no curiosity. But in the light of recent events even a little thing like this had its significance. At any rate, he would ask Beatrice about it.

Beatrice was in the drawing-room putting the finishing touches to the flowers. It would soon be dinner-time.

"I have just met your maid," Flower said. "What on earth is the matter with the girl? She looks as if she had seen a ghost. I hope to goodness the servants haven't been talking and making a lot of mischief about this story that a former lord of Maldon Grange walks the corridors at night. If there is one form of superstition I detest more than another, it is that."

"You would hardly call Annette a superstitious girl," Beatrice replied. "As a rule she is most matter of fact. But she came in just now with the strangest tale. She had been to the village to get something for me, and as she was rather late she came home through the pine wood. She declares that in the middle of the wood she saw two huge monkeys sitting on the grass gesticulating to one another. When I pointed out to her the absurdity of this idea, she was not vexed with me, but stuck to her statement that two great apes were there and that she saw them quite distinctly. Directly she showed herself they vanished, as if the ground had opened and swallowed them up. She doesn't know how she managed to reach home, but when she got back she was in great distress. Of course it is possible Annette may be right, in a way. I saw in a local paper the other day that there is a circus at Castlebridge, which has taken one of the large halls for the winter. The account that I read stated that one or two animals had escaped from the show and had caused a good deal of uneasiness in the neighbourhood. As Castlebridge is only about twenty miles from here, perhaps Annette was right."

Flower muttered something in reply. At first he was more disturbed than Beatrice was aware, but her news about the circus seemed plausible and appeared to satisfy him.

"It is very odd," Beatrice went on, "that we should have these alarming incidents simultaneously. For the last year or two we have led the most humdrum existence, and now we get two startling events in one day. Can there be any connexion between them?"

"No, of course not," Flower said roughly. "Tell the maid to keep her information to herself. We don't want to start a rumour that our woods are full of wild animals, or the servants will leave in a body. I'll write to the police to-morrow. If these animals are roaming about they must be captured without delay."

Flower made his way upstairs to his room to dress for dinner. Usually he had little inclination for social distractions, for his one aim in life was to make money. To pile up riches and get the better of other people was both his profession and his relaxation. Still, there were times when he liked to display his wealth and make his power felt, and Beatrice had a free hand so far as local society was concerned. But for once Flower was glad to know he would have something this evening to divert his painful thoughts into another channel. Try as he would he could not dismiss Black Care from his mind. It was with him when he had finished dressing and came down into the drawing-room.

Was it possible, he asked himself, there could be any connexion between the maid's story and the more startling events of the day? Surely it was easy for a hysterical girl to make a mistake in the dark.

But further debate was no longer practicable, for his guests were beginning to arrive. They were Beatrice's friends rather than his. From beneath his bushy eyebrows he regarded them all with more or less contempt. He knew perfectly well they would have had none of him but for his money. For the most part they were here only out of idle curiosity, to see such treasures as Maldon Grange contained. Only one or two perhaps were people after Flower's own heart. Well, it did not matter. Whatever changed the tenor of his thoughts and led his mind in new directions was a distinct relief. He sat taciturn and sombre till dinner was announced.

*CHAPTER V*

*UNDER THE TREES*

Wilfrid Mercer had walked back to Oldborough very thoughtfully. The events of the past hour or two appeared to have changed the whole current of his existence. He had parted with the old life altogether, and had set himself down doggedly to the humdrum career of a country practitioner. No more long voyages, no adventures more exciting than the gain of a new patient or the loss of an old one. He had not disguised from himself that life in Oldborough would be monotonous, possibly nothing but a sordid struggle. But he would get used to it in time, and perhaps even take an interest in local politics.

But already all was changed. It was changed by a simple accident to Samuel Flower. There was some inscrutable mystery here and, to a certain extent, Wilfrid held the key to it. It seemed to him, speaking from his own point of view, that he knew far more about the affair than Flower himself.

It was as well, too, that nothing should have happened to cause Beatrice Galloway any fear for the future. She might be puzzled and curious, but Wilfrid did not believe that she attached any significance to the piece of string. The string she found appeared to have been dropped by accident as, no doubt, it was; but behind that there lay something which spoke only to Wilfrid Mercer and Samuel Flower.

The more Wilfrid debated the matter, the more certain did he feel that Flower saw in this thing a deadly menace to himself. Wilfrid had not forgotten the look of livid fear on Flower's face when Beatrice handed the string to him. He had not forgotten the sudden cry that burst from Flower's lips. He did not believe that the ship-owner suffered from neuralgia. The most important point was to find out whether Flower understood the nature of the warning. Did he know that the mystery had been hatched in the Malay Archipelago? Did he know that the natives there had invented a mode of taking life which baffled even modern medical science? If Flower knew, then he might make a bold bid for life and liberty. If not, then his very existence was in peril.

So far Wilfrid's reasoning was clear. But now he struck against a knot in the wood and his plane could no go farther. What connexion was there between a prosaic British citizen like Samuel Flower and a bloodthirsty Malay on the prowl for vengeance? So far as Wilfrid knew, Flower had spent the whole of his life in London, where such contingencies are not likely to occur. The point was a difficult one to solve, and Wilfrid was still hammering at it when he reached home. Something like illumination came to him while dressing for dinner.

He wondered why he had not thought of it before. Of course, as a ship-owner, Samuel Flower would come in contact with all sorts and conditions of men. The crews of the Flower Line were drawn from all parts of the world. And amongst them Malays and Lascars figured prominently. Wilfrid recollected that there had been many Malays engaged in the mutiny on the _Guelder Rose_. Matters began to grow more clear.

The night was fine and bright and the sky full of stars as Wilfrid set out to walk to Maldon Grange. He would not be justified in the extravagance of a cab, for the distance was not more than four miles and he had been told of a short cut across the fields. At the end of half an hour a moon crept over from the wooded hills on the far side, so that objects began to stand out clear and crisp. Here was the path he must follow, and there were the spinneys and covers with which Maldon Grange was surrounded. Most of the fallen leaves were rotting under foot. The ride down which Wilfrid had turned was soft and mossy to his tread. He went along so quietly that he did not even disturb the pheasants roosting in the trees. He passed a rabbit or two so close that he could have touched them with his walking-stick. The rays of the moon penetrated the branches here and there and threw small patches of silver on the carpet of turf. Wilfrid had reached the centre of the wood where the undergrowth had been cleared away recently. Looking down the long avenue of trees, it seemed as if he were standing in the nave of a vast cathedral filled with great stone columns. For a moment he stood admiring the quiet beauty of it. Then he moved on again. His one thought was to reach his destination. He did not notice for a moment or two that a figure was flitting along the opening to his left or that another figure a little way off came out to meet it. When he did become aware that he was no longer alone he paused in the shadow of a huge beech and watched. He did not want to ask who these people were. Probably he was on the track of a couple of poachers.

But though the figures stood out clearly in the moonlight, Wilfrid could see no weapons, or nets, or other implements of the poaching trade. These intruders seemed to be little more than boys if size went for anything, and surely two poachers would not have seated themselves on the grass and proceeded to light a fire as these men were doing now. They sat gravely opposite one another talking and gesticulating in a way not in the least like the style of phlegmatic Englishmen. In a fashion, they reminded Wilfrid of two intelligent apes discussing a handful of nuts in some zoological garden. But then apes were not clothed, and these two strangers were clad. It was, perhaps, no business of his, but he stood behind the shadow of a tree watching them. He saw one reach out and gather a handful of sticks together; then a match was applied and the whole mass burst into a clear, steady and smokeless flame. The blaze hovered over the top of the sticks much as the flame of a spirit lamp might have done. With Wilfrid's knowledge of camp fires he was sure that a casual handful of sticks would never have given so clear and lambent a flame. He forgot all about his appointment at Maldon Grange, his curiosity overcoming every other feeling. He really must discover what these fellows were doing.

It was easy to creep from tree to tree until he was within thirty or forty yards of the two squatting figures. He saw that the fire was burning as brightly and clearly as ever. He saw one of the strangers produce a small brass pot into which he dropped a pinch or two of powder. Then the vessel was suspended over the fire, and a few moments later a thin violet vapour spread itself out under the heavy atmosphere of the trees until the savour of it reached the watcher's nostrils. It was a weird sort of perfume, sweet and intensely soothing to the nerves. It seemed to Wilfrid that he had never smelt the like of it before, and yet there was a suggestion of familiarity about it. Where had he been in contact with such vapour? How did it recall the tropics? Why was it associated with some tragedy? But rack his brains as he might he could make nothing of it. He felt like a man who tries to fit together the vague outlines of some misty dream. Doubtless it would come to him presently, but for the moment he was at fault. His idea now was to creep farther forward and try to see something of the faces of this mysterious pair. The mossy carpet under foot was soft enough, but there was one thing Wilfrid had not reckoned on. Placing his foot on a pile of dead leaves a stick underneath snapped suddenly with a noise like a pistol-shot. In a flash Mercer crouched down, but it was too late. As if it had been blown out with a fierce blast of wind, the fire was extinguished, the brass pot vanished, and the two figures dissolved into thin air. It was amazing, incredible. Here were the scattered trees with the moonlight shining through the bare branches. Here was the recently cleared ground. But where had those wanderers vanished? Wilfrid dashed forward hastily, but they had gone as swiftly and illusively as a pair of squirrels. Mercer drew his hand across his eyes and asked whether he were not the victim of hallucination. It was impossible for those men to have left the wood already. And, besides, there were the charred embers of the sticks yet warm to the touch, though there was no semblance of flame, or even a touch of sullen red. There was nothing but to go on to Maldon Grange and wait the turn of events. That these strangers were after no good Wilfrid felt certain. But whether they had or had not any connexion with the warning to Samuel Flower he could not say. He would keep the discovery to himself.

He was in the house at length. He heard his name called out as he entered the drawing-room. He was glad when Beatrice came forward, for he felt a little shy and uncomfortable before all these strangers.

"I am so glad you came," Beatrice murmured. "Stay here a moment. I have something important to say to you."

*CHAPTER VI*

*THE LAMP IS LIGHTED*

Beatrice emerged from a throng of chattering people presently and Wilfrid followed her into the hall.

"I hope you don't mind," she said, "but I should like you to see my maid. It may be nothing but a passing fit of hysteria, but I never saw her so nervous before. She went to the village on an errand this afternoon, and when she came back she told me she had been frightened by two large monkeys in the pine wood behind the house. She said that they vanished in a most extraordinary way. I should have put the whole thing down to sheer imagination if I had not known that some animals have escaped recently from the circus at Castlebridge."

"It is possible the girl spoke the truth," said Wilfrid, with a coolness he was far from feeling, "but I will see her with pleasure. I daresay if I prescribe something soothing you can send into Oldborough and get it made up."

Wilfrid returned by and by with the information that there was nothing the matter with the maid and that her story seemed clear and coherent. There was no time for further discussion, as Flower came forward and enlisted Wilfrid to make up a hand at bridge. The house was looking at its best and brightest now. All the brilliantly lighted rooms were filled with a stream of gaily dressed guests. The click of the balls came from the billiard-room. It seemed hard to associate a scene like this, the richest flower of the _joie de vivre_, with the shadow of impending tragedy, and yet it lurked in every corner and was even shouting its warning aloud in Wilfrid's ears. And only a few short hours ago everything was smooth, humdrum, monotonous.

"I hope you are not in any hurry to leave," Flower murmured as he piloted Wilfrid to the card table. "Most of these chattering idiots will be gone by eleven, and there is something that I have to say to you."

"I shall be at your service," Wilfrid said. "I will stay as long as you please. In any case I should like to have another look at your hand before I go."
