Now Sally remembered clearly that the folding doors had been wide open at the time of her first tour of investigation; as, indeed, had the door between the library and hall--now tight shut, else this light would have been perceptible in the hall as well.
It was undeniable, then, that since she had closeted herself up-stairs another person had entered the house--some one who had shut himself up there in the library for a purpose apparently as clandestine as her own. Or why such pains to mask the light, and why such care not to disturb the silence of the house?
To have gone on and made good an escape without trying to read this riddle would have been hardly human of the girl, for all her misgivings; she stole on to the folding doors with less noise than a mouse had made and put an eye to the crack, which, proving somewhat wider than she had imagined, afforded a fair view of the best part of the other room.
An electric chandelier was on full-blaze above the broad and heavy centre-table of mahogany, beyond which, against the farther wall, stood on the one hand a bookcase, on the other a desk of the roll-top type--closed. Above each of these the wall was decorated with trophies of ancient armour; between them hung a huge canvas in a massive gilt frame--the portrait of a beautiful woman beautifully painted. And immediately beneath the portrait stood a young man, posed in profound abstraction, staring at the desk.
He rested lightly against the table, his back square to Sally's view, revealing a well-turned head thatched with dark hair, clipped snugly by well-formed ears, and the salient line of one lean, brown cheek. But even so, with his countenance hidden, something conveyed a strong impression to the girl of a perplexed and disconcerted humour.
She was frankly disappointed. For some reason she had thought to discover a burglar of one or another accepted type--either a dashing cracksman in full-blown evening dress, lithe, polished, pantherish, or a common yegg, a red-eyed, unshaven burly brute in the rags and tatters of a tramp. But this man wore unromantic blue serge upon a person neither fascinating nor repellent. She could hardly imagine him either stealing a diamond tiara or hopping a freight.
But that he was of a truly criminal disposition she was not permitted long to doubt; for in another moment he started from his pensive pose with the animation of one inspired, strode alertly to the wall, stepped up on the seat of a chair beside the desk, and straining on tiptoes (though tolerably tall) contrived to grasp the handle of a short-bladed Roman sword which formed part of one of the trophies.
With some difficulty and, in the end, a grunt of satisfaction, he worked the weapon loose and, jumping down, turned to the desk, thrust the point of the sword between the writing-pad and the edge of the roll-top, forced the blade well in, and bore all his weight upon the haft of this improvised jimmy. Promptly, with a sound of rending wood, the top flew half-way up.
At this the man released the sword, which fell with a thump to the rug at his feet, pushed the top as far back as it would go, and, bending over the desk, explored its rack of pigeonholes and drawers. One of the latter eventually yielded the object of his search; he took from it first a small automatic pistol, which he placed carelessly to one side, then a small leather-bound book whose pages he thumbed in nervous haste, evidently seeking some memorandum essential to his ends. This found, he paused, conned it attentively for an instant, then turned and took the book with him across the room beyond the bookcase, thus vanishing from the field of Sally's vision.
Now was her chance to slip down-stairs and, undetected, away. But, surprisingly enough, she proved of two minds about advantaging herself of the opportunity. To begin with, she was no more afraid--at least, not to any great extent. What, she argued scornfully, was one man, after all?--especially one who had no more lawful business than she upon those premises! She wasn't afraid of men; and even were this one to catch her watching him (something Sally meant to take good care he shouldn't) he could hardly denounce her to the police. Besides, what was he up to, anyhow, over there in that corner, out of sight? She simply had to know the meaning of those noises he was making.
