And there the matter rested, save that, upon arrival in Mojave, the bridge was found to be missing. The emissary from Mojave seemed to remember a dark-faced stranger who had been seated opposite them in the train, but that was all; the man had jostled against his charge upon alighting; the last proof, if indeed it might be called a proof, was gone.

Annister frowned thoughtfully, his mind upon that canceled check in his pocket. And he was remembering one other thing, and that was the square of paper which he had found among his father’s effects, for on it had been a name, or, rather, two: the name of Hamilton Rook, and of another, unknown to Annister. And as to that Axworthy case, it was common knowledge that lunatics, for instance, entertained frequently the delusion that they were people of importance. There was nothing new in that.

Somehow, it seemed to him that he held in his hands the pieces of a jig-saw puzzle that, even if put together, made but a patchwork of motives and design, which yet, if he could but find the key, would be as clear as crystal.

That paper found in his father’s office; the interview with Childers, at Washington; the long trip westward; the warning message on the train; the big man with the ice-blue eye and the square jaw of a fighter; the attack in the hotel; the meeting with Rook, and the meeting with the girl; the finding of that canceled check—and, last, the matter of those queerly related news items just under his hand—these made a pattern to be unraveled only by the warp and woof of Fate.

And the chance meeting with the bearded stranger at the corner of the street: consider how he would, Annister’s mind kept turning backward to that meeting and those eyes that were like the eyes of a damned soul, malignant, cold, in their abysmal, cold cruelty of discarnate Evil.

Discarnate! That was it; that would express it; for the man, as he recalled him, seemed somehow less than human; there had been about him an aura, an emanation, that was like a tide rising from the depths, from darkness unto darkness....

Annister was scarcely superstitious, but he was again conscious of that icy chill; he shivered, as a man is said to shiver when, according to an ancient superstition, someone is said to be walking over his grave.

He rose, walking to the window, to peer outward into the sunwashed street. The coil was tightening; he felt it; and he was but one man against many. And knowing what he knew, or suspecting what he suspected, it seemed to him all at once that the sunlight had flattened to a heatless flaming of pale radiance; there seemed a menace in it, even as there seemed a menace in the very air, a waiting, a tension, like a fine wire drawn and singing at a pitch too low for sound.

Abruptly he heard a sound; it was like the scratching of a rat in the wainscot, faint and thin. His door was locked.

Now, looking at it, the knob turned, slowly, stealthily. He could see it turning.
