Perplexed, he examined the rear windows. They were closed and locked, as when he had left. Opening them, he peered out and down the fire-escape; he had always had a notion that anybody foolish enough to want to burgle his rooms would find it easy to effect an entrance via the fire-escape, whose bottom rung was only eight feet or so above the level of the backyard. And now, since the Twenty-ninth Street houses had been torn down, lending access easy via the excavation, such an attempt would be doubly easy.
But he had every evidence that his rooms hadn’t been broken into by any such route; although—of course!—an astute burglar might have thought to cover up his tracks by relocking the windows after he had entered. On the other hand, the really wise marauder would have almost certainly left them open to provide a way of escape in emergency.
Baffled and wondering, Staff returned to his study. An examination of the hall-closet yielded nothing illuminating. Everything was undisturbed, and there wasn’t room enough therein for anybody to hide.
He shut the closet door and reviewed the study more carefully. Not a thing out of place; even that wretched bandbox lay where he had kicked it, with a helpless, abused look, the dented side turned pitifully to the light—much like a street beggar exposing a maimed limb to excite public sympathy.
He struggled to think: what did he possess worth stealing? Nothing of any great value: a modest collection of masculine jewelry—stick-pins and the like; a quantity of clothing; a few fairly good pictures; a few rare books. But the merest cursory examination showed that these were intact, one and all. What cash he had was all upon his person. His desk, where the lamp had been lighted, held nothing valuable to anybody other than himself: manuscripts, account books, some personal papers strictly non-negotiable. And these too proved undisturbed.
Swinging round from the desk, he rested his elbows on his knees, clasped his hands, and lapsed into the most profound of meditations; through which he arrived at the most amazing discovery of all.
Very gradually his eyes, at first seeing not what they saw, focussed upon an object on the floor. Quite excusably he was reluctant to believe their evidence. Eventually, however, he bent forward and picked up the thing.
It lay in his hand, eloquently absurd—in his study!—a bow of violet-coloured velvet ribbon, cunningly knotted, complete in itself. From its reverse, a few broken threads of silk hung, suggesting that it had been originally sewn upon a gown, or some other article of dress, from which it had been violently torn away.
The thing was so impossible—preposterous!—that he sat as if stunned, eyes a-stare, jaw dropping, wits bemused; until abruptly roused by the sharp barking of a taxicab horn as it swung round the corner of Fourth Avenue and the subsequent grumble of its motor in the street below.
Thrusting the velvet knot into his pocket he ran down and opened the front door just as Alison gained the top of the brownstone steps.
