him.
Betty was as good as her word. She made no attempt to prolong her stay, but deposited her purchases on the hall-table, and promised that she or her mother would come about seven in the morning.
"Will you need to be called, sir?" she inquired, as an afterthought.
"Well, yes. I'm a sound sleeper," he assured her gravely.
The statement was true, but it required qualification. A man who had slept many a night under conditions that demanded instant wakefulness if any sinister sound threatened his very existence, did not rank in the class of sound sleepers known to quiet Elmdale.
Thereafter he cooked a meal of eggs and bacon, tea and toast, smoked, rambled in the garden, read, thought a good deal, and went to bed.
The light in his room was extinguished soon after ten o'clock. About half-past eleven, little more than twelve hours from the time he had first heard of "the house 'round the corner," he was aroused by a loud crash in the hall. He was up in an instant, laughing at the success of a booby trap compacted of the Burmese gong, some thread, and a piece of wood set as a trigger. His feet were not on the floor before the front door banged, and, hurrying to the window, he saw Betty Jackson flying down the path for dear life. He could not be mistaken. In that northern latitude a midsummer night is never wholly dark. He not only recognized the girl, but could note her heaving shoulders as she sobbed hysterically in her flight.
"I'm sorry if you're badly scared, my country maid, but you asked for it," he said aloud. "Now I think I'll be left to undisturbed slumber till seven o'clock."
Therein he erred. He had not quitted the window, being held by the solemn beauty of the gray landscape, ere a heavy thud, and then another, and yet a third, reached his ears. He might not have localized the first, but its successors came unmistakably from the attic. After a few seconds, the three knocks were repeated, and now he adjudged them to the precise bounds of the trap-door.
Slipping an automatic pistol into the pocket of his pyjama suit—merely as a precaution against the unforeseen, though he was a man devoid of fear, he took an electric torch from a drawer, but knew better than to bring it into use until its glare would disconcert others—not himself. He thrust his bare feet into slippers, unlocked the bedroom door, and passed out on to the landing.
"Now to unveil Isis!" he thought, as he felt for the first step of the upward stairway. It needed one of steel nerve and fine courage to creep about a strange house in the dark—a house where ill deeds had been done, and in which their memories lurked—but Robert Armathwaite had gone through experiences which reduced the present adventure to the proportions of a somewhat startling prank, closely akin to the success of the stratagem which had routed Betty Jackson.
And, as he mounted the stairs, keeping close to the wall, and thus preventing the old boards from creaking, again came those ominous knocks, louder, more insistent; but whether threatening or merely clamorous he could not decide—yet.
CHAPTER III
A MIDNIGHT SEANCE
Armathwaite had a foot on the upper landing when a stifled sob reached his ears, and a determined, almost angry, stamping or hammering shook the trap-door. One element, then, of the mystery attached to this reputedly ghost-ridden house was about to be dispelled. When James Walker shot the bolt which rendered the door as unyielding as the stout rafters which incased it, he had unwittingly imprisoned someone in the attic loft; and the someone, tiring of imprisonment, was making loud demand for release. Moreover, Betty Jackson was in the secret. She knew of the intruder's presence, but had not learnt the particular mode of concealment adopted—hence her renewed efforts to gain admission, her use of the ladder, and her somewhat daring visit during the dead hours of the night.
Now, Armathwaite scouted the notion of a couple of village women like Mrs. Jackson and her daughter being in league with midnight robbers, or worse. Even if some thievery was in prospect, they could not possibly have arranged that certain unknown miscreants should hide beneath the roof, since the arrival of Walker with an unexpected tenant was evidently the last thing they had dreamed of.
Therefore, smiling at the humor of the incident, he had to simulate a sternness he was far from feeling when he cried:
"Stop making that noise! Who are you, and how did you come to get yourself locked in in this way?"
"Please let me out!" came the muffled reply. "I'll explain everything—I will, indeed!"
Thereupon, Armathwaite was more surprised than ever. The appeal, though tearful and husky, was precisely opposite in character to that which he anticipated. He looked for gruff entreaty in the accents of the country of broad acres. What he actually heard was a cultured voice, a voice with a singularly soft and musical enunciation, and its note was of complaint rather than petition.
"All right!" he cried, hardly suppressing a laugh. "I'll bring a chair and draw the bolt. I suppose you can lower the ladder yourself?"
"Of course I can—I drew it up!"
Again, the answer did not fit in with the conditions. But Armathwaite secured the same chair which Walker had used, pressed the button of the electric torch, and, having forced the bolt out of its socket, raised the door a few inches.
"Catch hold!" he said. "I'll show you a light."
The door was lifted, and he glimpsed a beardless face peering from the inner void. He sprang to the floor, put the chair on one side, and awaited developments. Soon the ladder appeared, and was adjusted. Then came two neat but strong brown brogues, with slim-ankled black stockings to match, and the turned-up ends of a pair of gray, flannel trousers. The owner of these articles of attire sat for an instant on the edge of the trap, as though reluctant to descend further, and Armathwaite noticed, to his very great bewilderment, that the black stockings were of silk.
"Will you kindly promise not to grab my legs as I come down?" said the voice.
"I have not the slightest desire to grab your legs, or your neck, for that matter, if you behave yourself," said Armathwaite.
"You don't understand, of course," came the curiously dignified protest; "but I am not misbehaving myself, and have no intention of so doing. This ridiculous thing would not have happened if that silly young fop had not fastened the trap-door. I can't imagine why he did it. It was no business of his, at any rate. And may I ask who you are?"
"I'll answer all polite inquiries, and, it may be, put a few on my own account, when you favor me with a closer view," said Armathwaite, not without a tinge of sarcasm in his politeness.
"Oh, this is too stupid for words!" was the petulant reply, and the speaker swung into sight. The ladder was tilted steeply, and the steps were narrow. Apparently, the young gentleman in a gray flannel suit who materialized in this manner preferred to gaze at his rescuer rather than adopt the safer method of descent which involved a momentary turning of his back. Possibly, too, he was more nervous than his remarks betokened, for he was yet some distance from the floor when the lower-most foot slipped, and he fell. The toe of the other foot caught in a rung, and he was thrown violently into Armathwaite's arms, who, to save
