Willard Lyall came down to breakfast and glanced at his mail. it was a fairly large pile, but nothing more than usual. Mercia often twitted him with the fact that he seemed to do most of his business by correspondence at home.
He tossed one or two letters aside, matters of small moments, thrust one or two others into an inside pocket without opening them and then picked up a plain post-card. it was addressed to him in neat, upright capitals and note the London post-mark across the stamp. The date of posting was blurred and scarcely decipherable. He turned it over in curiously . on the reverse side also in black print letters, was a single sentence.
A slow frown spread over his face as he read it. His hand shook and he dropped the card suddenly to the table. There was a sickly, unhealthy pallor crawling slowly over his skin, but the dark brows had come down over his eyes like a thunder cloud.
He read the extraordinary thing again and a look of awful shock came into his eyes.
"Do not leave your house on Monday night if you value your life."
Stark and forbidding the words glared up at him from the post-card. They seemed to be vital, alive. They were grinning up at him in a mute, malignant stare.
He stared back at the thing as though in a mesmeric trance. It was the worst shock he had ever had in his life. For fifteen years, Willard Lyall had plied his trade behind an impenetrable mask of unimpeachable gentility.
And here, like a thunderbolt out of the cloudless blue came a dumb messenger in black and white to stun him with the knowledge that his secret was not only suspected but definitely known.
He mopped his forehead with a trembling hand and glanced once more at the thin red wafer, impressed with the myriad lines of a fingerprint. It lay on the white card like a drop of blood sinister and brutally significant.
At first he thought it must be some vulgarly offensive practical joke. but he rejected the thought almost as soon as it was formed. His friends were not the kind who would send such things as that through the open post. and his own guilty conscience, his own instinctive knowledge told him that this was no joke.
He broke into a cold sweat. He saw the full horror of the thing in a single, disruptive seconds. He had been living in a fool's paradise.
And ahead the cold, chill vista of the years of degraded slavery. it was all there the mud-slinging, the callous, horrible, inhumanity of the showdown, the amazement, the anger, the sympathy, the mockery of his friends he saw the beginning and the end of it all in that card.
He pulled himself up with a jerk. He had just noticed his hand it was shaking like a leaf.
"Good Lord!" he muttered. "This won't do. Get a grip on yourself man , pull yourself together."
He picked up the card and examine it closely. no date, no clue in the writing, no address, no anything even the post-mark was so smudge as to be unreadable. it was posted at the G.P.O. he could tell that much from the code initials. But the actual time of posting and the horary letters were a black bodge. He could not even see whether they were a.m or p.m.
After a few minutes hard thinking, he stood up and there was a gleam of battle in his eyes.
"So they think they can frighten me off as easily as that, do they?" he muttered to himself. " There's a renegade in the camp somewhere---- a renegade who thinks he can slip in and pick the plums after all the months of scheming and planning.... well, we shall see about you Mr. Judas."
Then after a little while, he added. "Either that or someone has got cold feet. and cold feet are not to be encouraged in this profession. They leads to cold cells."
He thrust the grim warning into his pocket as a light footstep sounded in the hall outside.
Mercia came into the breakfast room smiling a merry morning greeting to her father.
Lyall as cool and unperturbed as though such things as anonymous warnings were something infinitely removed from his sphere of life smiled back at her and chaffed her about the fresh healthiness of her colour.
"Rouge so early in the day?" he protested. "My dear girl please!"
"That's not rouge," expostulated Mercia, rubbing her cheeks with a handkerchief to demonstrate the irrefutable naturalness of her colour. "That's a cold tub."
"Indeed!"
"Yes indeed every morning Eight o'clock. Whooshter! Brrh! It was icy enough this morning anyway. You wouldn't look so unnaturally white in the morning if you risked a cold bath anyway."
Lyall looked at her critically.
"white? Why? Am I white this morning?" he asked.
"Only in so far as you look as though you have just seen your own ghost, or-----or had an atrocious night last night."
"Which I have not; and did not; replied Lyall suavely.
"I don't suppose you did. But there's another thing you might do for the benefit of your health, and such others as may be concerned. It isn't anything drastic either, like signing the pledge or swearing off smokes or wintering on the Riviera."
"And that is?"
"Come down to Brighton to see that night firing experiment of Mr. Dain's. An exciting night trip in the vigorous sea air with some fun in the wind would do you more good than a whole week on the golf Links."
Lyall stiffened perceptibly. He did not answer. He was thinking at the lightning speed. the mention of Valmon Dain's name had sent his memory rocketing back to Dain's visit the previous evening. And he sensed an odd connection, an unsettling coincidence between that visit with its pressing invitation to witness a private Admiralty test and the arrival of that grisly thing in his pocket.
Yes there certainly was something very unusual about that visit. The invitation itself now, that was unusual. Dain decidedly was not the type who admitted others into the confidence of his experiments and Inventions.
And the lateness of the hour too. That was more than unusual. It must have been some time after midnight before he arrived at Greydene. That was a thing he had never done before. He had not even phoned his intentions. He had just landed up there, obviously on the spur of the moment. And his excuse for declining to take the ladies along with him after Lyall had intimated his inability to accompany them. that was very weak, very weak indeed..
And yet, how on earth did Valmon Dain come to know anything about me?
By what miraculous means did he know that in the early hours of Tuesday morning we proposed to burgle the Duchess of Renburgh's jewel collection?
The more he thought about it, the more hopelessly involved it became.
Throughout breakfast Lyall was very quiet and uncommunicative. To cover his very unusual mealtime restraint he pretended a deep absorption in his morning papers. As soon as he had left the house, Mercia and her mother exchange meaning glances. "Dad seems very reserved this morning mum," said Mercia. "Probably worried about business affairs, my dear," said Mrs. Lyall. "You will come to know men in times as well as I do. And I think I know Willard very well. When a man is having a harassing time in the city, he resorts to silence." Mercia shrugged."I don't think it's mere worry," she said quietly. "I've seen dad when he has had worry before. I've seen him when he has been like a bear with a sore head. But I've never seen him like he was this morning when I came into the breakfast room. I know dad, and it seemed to me that he had received some awful shock."Mrs. Lyall looked very perturbed."A shock
"You see," continued Lyall ; "it means that somewhere in London there is an UNKNOWN SPY who knows as much about my movements as I do myself. It must be obvious to even the meanest intelligence that he is fully aware of my intentions regarding the Duchess of Renburgh's jewels. It is or ought to be equally obvious that he has already notified the police of my intentions or perhaps I ought to say our intentions. otherwise why should he warn me? And again, why has he warn me and not the others? But chiefly, who the devil is he?"The cold, chill note had gone out of Lyall's voice. His easy assumption of casual detachment fell away and he uttered the last words with a rasping asperity."I've been thinking matters over very closely this morning," he went on, "and I've come to the conclusion that here, I'm this warning is a clue to the biggest mystery we have ever known. here is a connecting link with something that has been gnawing at my thoughts for weeks." He br
Two miles away In an office high up among the roofs in kingsway, Valmon Dain removed a contact key from a red-lit dial and mopped his forehead."So!" he muttered, and dabbed at his forehead again. "murder, is it? eh? Well that is a word that is guaranteed to put a different colour on anything."He sat down gingerly on the edge of a chair and lost himself in a teeming intensity of thought.His mind had gone on ahead of the days and he too was standing in the black darkness of the area by the kingsland mews. He saw the dark figures slinking along from shadow to shadow, elusive as the ghost of flitting bats. saw them mustering in the silence and waiting, waiting for the man who would not be there.And then the sudden uprising of other shadows from the blackness avenging shadows which advanced with malignant swiftness from nowhere. the quick sharp scuffle, and then the fierce passionate denunciation of Willard Lyall, the traitor, the m
Mercia halfway through a rippling medley of sharps and naturals stopped with a jerk, her white fingers poised daintily above the keys."What was that?" she said in a puzzle voice to herself. What had seemed just like an unmistakable bump had just sounded in the next room. She thought something must have fallen over but one can never tell with a half a dozen servants busy about the house. They make such queer noises at times, shifting furniture about and doing the myriad things that only servants seem to find necessary to do."That you dad?" she called. And no answering hail came from the next room."Dad are you there?" she called again rising from her stool. And there was silence in the study.Mercia ran in. Her father was lying prone on the floor, his face buried in the thick pile of the carpet almost suffocating."mummy come quickly," she cried through the door."Dad has fainted quickly phone the doctor.
Dain read all about the affair while traveling to his office. He got back from his Brighton engagement some time after midday and went on from Victoria by tube. He slipped unobtrusively into an end seat and began to read. He wasn't at all elated, or even concerned about the test performance of his new gun sights he has already satisfied himself as to their complete perfection before even getting into communication with the Admiralty.And then a ghost of a smile played on the corners of his mouth as he took out his pocket-book. The train had stopped at a station and had filled up. There were strap-hangers pressing against his knees ; one succeeded in treading on his feet-- a man with a villainously dirty countenance and ghastly cast in his eye.Dain looked up in mild remonstrance."sorry guv," said the unwashed one and took a fresh grip on his strap.Dain smiled a frosty acknowledgement and resume his attention to his pocket-book.
"What are you looking so peeved about?" he inquired truculently. "He can't do us no good while he stays alive, cab he?""Not that I'm aware of," said Lyall. "But at the same time, you'll admit there are difficulties. I don't even know that this is the man we're looking for."well, perish my bones!" snorted Tansy. "I saw him with my own eyes, didn't I? saw him pull out his book and write the names down. saw him turn over the pages with 'eaps of other cases wrote down on 'em ; saw him take the names out of the paper and stick 'em down under the silver Arrow. And blimey!----- I saw the writing' , too! You can't get away from that!""Y-yes, I know," said Lyall defensively. "But you also said his name was Dent, and that he has an office in kingsway. That, I know for a positive fact, is untrue.""Is it? Well, maybe you know more about him than I do."There was something more than a note of grievance in Tansy's voice. there w
It was not until nearly ten o'clock that evening that Valmon Dain completed his preparation for the reception of Willard Lyall.He had been working steadily through the afternoon in his workshop out at Hendon. It was a fairly large room, high and airy and was built on to the main building as a sort of an annexe with wide benches on three sides. The bench at the top end was fitted out essentially as a chemical laboratory. Back at the other end, against the door were his writing desk and technical library for Valmon Dain recorded the results of each tiny phase of an experiment as he arrived at it. There were ten great shelves of monumentally scientific times, each a standard work of reference on some aspect of Dain's own activities. In front of them was his desk----a roll top.Dain was sitting at it, writing ; the clock hands neared the hour of ten. His pen jotted neatly over the letter-card. "TO THE CHIEF COMMISSIONER,
suddenly he stiffened. The little disc had blazed to light ."Ah! our visitor is at the garden gate," he said gently . He folded his arms on the desk and his head lolled forward. To all appearances, Valmon Dain had fallen asleep in his chair. But one eye steady and unwinking, stared at the little box on the table waiting for the white light to flash out, telling him that Willard Lyall was at the laboratory door.A face peered in at the window, a face that slid cautiously inch by inch into full view behind the glass. It was Lyall. There was a frown of disappointment on his forehead ; he had not expected to find Dain still up.But the frown gave way to a slow smile of satisfaction when he saw all that was in the room. Fate seemed to have played Dain right into his hands.With a quick All-embracing look, he inspected the interior of the workshop. The face moved from the window, and for a tense, long-drawn-out minutes the
