ill. Lady Louisa is in Yorkshire, and I am making arrangements

which will close a long-standing feud.

"Write me here if necessary, but kindly keep back all business or other communications, save those of a very urgent character, for at least a week or perhaps ten days.

"Sorry for this enforced absence from town. It simply cannot be avoided, and I am sure you will leave a detailed explanation until we meet. I have signed the inclosed annual report of the home. Will you kindly forward it to the secretary? Yours sincerely,

"PHILIP ANSON."

Grenier dictated this epistle from a carefully composed copy. He understood the very friendly relations that existed between Philip and his chief agent, and he thought that in adopting a semi-apologetic, frankly reticent tone, he was striking the right key.

The concluding reference to the Mary Anson Home was smart, he imagined, while the main body of the letter dealt in safe generalities.

Naturally, he knew nothing of the conversation between the two men on this very topic a couple of months earlier.

But Langdon's ample confessions had clearly revealed Philip's attitude, and the unscrupulous scoundrel was willing now to dare all in his attempt to gain a fortune.

While he was dining a telegram was handed to him:

"You forgot to send your address, but Mr. Abingdon gave it to me. So grieved you are detained. What about blue atom?

"EVELYN."

Did ever woman invent more tantalizing question than that concluding one? What was a blue atom? No doubt, creation's scheme included blue atoms, as well as black ones and red ones. But why this reference to any particular atom? He tried the words in every possible variety of meaning. He gave them the dignity of capitals. BLUE ATOM. They became more inexplicable.

In one respect they were effective. They spoiled his dinner. He had steeled himself against every possible form of surprise, but he was forced to admit that during the next three days he must succeed in persuading Evelyn Atherley that Philip Anson was alive, and engaged in important matters in Yorkshire. That was imperative--was his scheme to be wrecked by a blue atom?

Moreover, her query must be answered. His promise to write was, of course, a mere device. It would be manifestly absurd to send her a typewritten letter, and, excellently as he could copy Philip's signature, he dared not put his skill as a forger to the test of inditing a letter to her, no matter how brief. Finally he hit upon a compromise. He wired:

"Stupid of me to omit address. Your concluding sentence mixed up in transmission. Meaning not quite clear. Am feeling so lonely.

"PHILIP."

Then he tried to resume his dinner, but his appetite was gone.

In postal facilities, owing to its position on a main line, York is well served from London. At 9 P. M. two letters, one a bulky package and registered, reached him.

The letter was from Mr. Abingdon. It briefly acknowledged his telegram, stated that a man in the Athenæum, who knew Sir Philip Morland, had informed him, in response to guarded inquiries, that the baronet was exceedingly well off, and called attention to some important leases inclosed which required his signature.

The other note was from Evelyn. It was tender and loving, and contained a reference that added to the mystification of her telegram.

"In the hurry of your departure yesterday," she wrote, "we forgot to mention Blue Atom. What is your opinion? The price is high, certainly, but, then, picture the joy of it--the only one in the world!"

And, again, came another message:

"I referred to Blue Atom, of course. What did the post office make it into?

"EVELYN."

Blue Atom was assuming spectral dimensions. He cursed the thing fluently. It was high priced, a joy, alone in solitary glory. What could it be?

He strolled into the station, and entered into conversation with a platform inspector.

"By the way," he said, casually, "have you ever heard of anything called a blue atom?"

The man grinned. "Is that another name for D. T.'s, sir?"

Grenier gave it up, and resolved to postpone a decision until the next morning.

By a late train Philip's portmanteau arrived. It was locked, and the key reposed in the safe. Green, it ultimately transpired, solemnly opened the safe in the presence of the housekeeper and butler, locked it again without disturbing any of the other contents, and handed the key to the butler, who placed it in the silver pantry.

In the solitude of his room, Grenier burst the lock. The rascal received one of the greatest shocks of his life when he examined the contents--a quantity of old clothing, some worn boots, a ball of twine, a bed coverlet, a big, iron key, the tattered letters, and a variety of odds and ends that would have found no corner in a respectable rag shop.

He burst into a fit of hysterical laughter.

"Ye gods and little fishes!" he cried. "What a treasure! The Clerkenwell suit, I suppose, and a woman's skirt and blouse. Old-timers, too, by their style. His mother's, I expect. He must have been fond of his mother."

At that moment Jocky Mason, beetle-browed and resentful, was reading a letter which reached his lodgings two hours before his arrival, in an envelope bearing the ominous initials--O. H. M. S.

It was from the Southwark Police Station.

"SIR: Kindly make it convenient to attend here to-morrow evening at 8 P. M. Yours truly,

"T. BRADLEY, Inspector."

The following day it was Mason's duty to report himself under his ticket-of-leave, but it was quite unusual for the police to give a preliminary warning in this respect. Failure on his part meant arrest. That was all the officials looked after.

"What's up now?" he muttered. "Anyway, Grenier was right. This gives me a cast-iron alibi. I'll acknowledge it at once."

His accomplice, hoping to obtain sleep from champagne, consumed the contents of a small bottle in his bedroom, while he scanned the columns of the local evening papers for any reference to a "Seaside Mystery" on the Yorkshire coast.

There was none. Anson's body had not been recovered yet.

Before going to bed, he wound Philip's watch. He examined it now with greater interest than he had bestowed on it hitherto.

Although silver, it appeared to be a good one. He opened the case to examine the works. Inside there was an inscription:

"Presented to Philip Anson, aged fifteen years, by the officers and men of the Whitechapel Division of the Metropolitan Police as a token of their admiration for his bravery in assisting to arrest a notorious burglar."

Beneath was the date of Mason's capture.

"Where was I ten years ago?" he mused.

He looked back through the soiled leaves of a sordid record, and found that he was then acting in a melodrama entitled "The Wages of Sin."

And the wages of sin is death! The drama insisted on the full measure of Biblical accuracy. Altogether, Grenier lay down to rest under unenviable conditions.

He dreamed that he was falling down precipices, and striking sheets of blue water with appalling splashes. Each time he was awakened by the shock.

But he was a hardy rogue where conscience was concerned, and he swore himself to sleep again. Rest he must have. He must arise with steady head and clear brain.

He was early astir. His first act was to send for the Yorkshire morning papers. They contained no news of Philip Anson dead, but the local sheet chronicled his arrival at York.

This was excellent. The banker would see it. A few printed lines carry great weight in such matters.

Then he signed the leases, dispatched them in a typewritten envelope and telegraphed:

"Documents forwarded this morning. Please meet wishes expressed in letter."

"Surely," he reflected, "Abingdon will not give another thought to my proceedings. Philip Anson is not a boy in leading strings."

He wired to Evelyn:

"Sorry for misunderstanding. Blue Atom must wait until my return."

Here was a way out. Whatever that wretched speck of color meant, it could be dealt with subsequently.

But Evelyn's prompt reply only made confusion worse confounded:

"Delay is impossible. The man has put off the duchess two days already."

So a man, and a duchess, and a period of time were mixed up with a blue atom. He must do something desperate; begin his plan of alienation sooner than he intended. He answered:

"Too busy to attend to matter further. Going to Leeds to-day. Letters here as usual."

And to Leeds he went. Residence in York was a fever--a constant fret. In Leeds he was removed from the arena. He passed the afternoon and evening in roaming the streets, consumed with a fiery desire to be doing, daring, braving difficulties.

But he must wait at least another day before he could lay hands on any portion of Philip Anson's wealth save the money stolen from his pockets.

At the hotel there was only one letter and no telegrams.

The London bankers wrote:

"We beg to acknowledge yours of yesterday. Your cash balance at date is twelve thousand four hundred and ten pounds nine shillings one penny. Your securities in our possession amount to a net value at to-day's prices of about nine hundred and twenty thousand pounds, including two hundred and fifty thousand pounds Consols at par. We will forward you a detailed list if desired, and will be pleased to realize any securities as directed.

"Kindly note that instructions for sale should be given in your handwriting, and not typed."

There was joy, intoxicating almost to madness, in this communication, but it was not unleavened by the elements of danger and delay.

His signature had been accepted without demur; he could control an enormous sum without question; these were the entrancing certainties which dazzled his eyes for a time.

But it was horribly annoying that a millionaire should keep his current account so low, and the concluding paragraph held a bogey, not wholly unforeseen, but looming large when it actually presented itself.

The memorandum in Philip's handwriting on Evelyn's letter was now thrice precious. He hurriedly scrutinized it, and at once commenced to practice the words.

"Devonshire" and "Sharpe" gave him the capitals for "Dear Sirs." He was at a loss for a capital "C," but he saw that Philip used the simplest and boldest outlines in his caligraphy, and he must risk a "C" without the upper loop. In "Lady M.," too, he had the foundation of the "£" to precede the requisite figures. Soon he framed a letter in the fewest words possible:

"Yours of to-day's date received. Kindly sell Consols value one hundred and fifty thousand pounds, and place the same to my credit."

He copied it again and again, until it was written freely and carelessly, and every letter available compared favorably with the original in his possession. Then he posted it, thus saving a day, according to his calculations.

With this missive committed irrecoverably to the care of his majesty's mails, Victor Grenier's spirits rose. Now, indeed, he was in the whirlpool. Would he emerge high and dry in the El Dorado of gilded vice which he longed to enter, or would fortune consign him to Portland again--perchance to the scaffold? He could not say. He would not feel safe until Philip Anson was a myth, and Victor Grenier a reality, with many thousands in the bank.

Already he was planning plausible lies to keep Mason out of his fair share of the plunder. A few more forged letters would easily establish the fact that he was unable to obtain a bigger haul than, say, fifty thousand pounds.

And what did Mason want with twenty-five thousand pounds? He was a gnarled man, with crude tastes. Twenty, fifteen, ten thousand would be ample for his wants. The sooner he drank himself to death the better.

With each fresh cigar Mason's moiety shrank in dimensions. The murder was a mere affair of a vengeful blow, but this steady sucking of the millionaire's riches required finesse, a dashing adroitness, the superb impudence of a Cagliostro.

But if his confederate's interests suffered, the total fixed in Grenier's original scheme in nowise became affected.

He meant to have a hundred thousand pounds, and he firmly decided not to go beyond that amount. His letter to the bankers named one hundred and fifty thousand pounds, and he calculated that by stopping short at two-thirds of the available sum he would not give any grounds for suspicion or personal inquiry.

Yet he would shirk nothing. Mr. Abingdon and Miss Atherley must be avoided at all events; others he would face blithely. He took care to have ever on the table in his sitting room a goodly supply of wines and spirits.

If anyone sought an interview, it might be helpful to sham a slight degree of intoxication. The difference between Philip drunk and Philip sober would then be accounted for readily.

But rest--that was denied him. It was one thing to harden himself against surprise; quite another to forget that disfigured corpse swirling about in the North Sea.

He wished now that Philip Anson had not been cast forth naked. It was a blunder not to dress him, to provide him with means of identification with some unknown Smith or Jones.

When he closed his eyes he could see a shadowy form wavering helplessly in green depths. Never before were his hands smeared with blood. He had touched every crime save murder.

Physically, he was a coward. In plotting the attack on Philip, he had taxed his ingenuity for weeks to discover some means where he need not become Mason's actual helper. He rejected project after project. The thing might be bungled, so he must attend to each part of the undertaking himself, short of using a bludgeon.

He slept again and dreamed of long flights through space pursued by demons. How he longed for day. How slowly the hours passed after dawn, until the newspapers were obtainable, with their columns of emptiness for him.

A letter came from Evelyn. It was a trifle reserved, with an impulse to tears concealed in it.

"I asked mother for fifty pounds," she wrote, "so the Blue Atom incident has ended, but I don't think I will ever understand the mood in which you wrote your last telegram. Perhaps your letter now in the post--I half expected it at mid-day--will explain matters somewhat."

He consigned Blue Atom to a sultry clime, and began to ask himself why Mr. Abingdon had not written. The ex-magistrate's reticence annoyed him. A letter, even remonstrating with him, would be grateful. This silence was irritating; it savored of doubt, and doubt was the one phase of thought he wished to keep out of Mr. Abingdon's mind at that moment.

As for Evelyn, she mistrusted even his telegrams, while a bank had accepted his signature without reservation. He would punish her with zest. Philip Anson's memory would be poisoned in her heart long before she realized that he was dead.
