“More or less.” Chester nodded ponderously. “He’s the pet in so far as the Mater’s capable of petting any one but herself. Anyway, she’s never ragged Rex as much as the rest of us.”

Again Vance went to the great window above the East River, and stood looking out. Suddenly he turned.

“By the by, Mr. Greene, did you find your revolver?” His tone had changed; his ruminative mood had gone.

Chester gave a start, and cast a swift glance at Heath, who had now become attentive.

“No, by Gad, I haven’t,” he admitted, fumbling in his pocket for his cigarette-holder. “Funny thing about that gun, too. Always kept it in my desk drawer—though, as I told this gentleman when he mentioned it”—he pointed his holder at Heath as if the other had been an inanimate object—“I don’t remember actually having seen it for years. But, even so, where the devil could it have gone? Damme, it’s mysterious. Nobody round here would touch it. The maids don’t go in the drawers when they’re cleaning the room—I’m lucky if they make the bed and dust the top of the furniture. Damned funny what became of it.”

“Did you take a good look for it to-day, like you said?” asked Heath, thrusting his head forward belligerently. Why, since he held to the burglar theory, he should assume a bulldozing manner, I couldn’t imagine. But whenever Heath was troubled, he was aggressive; and any loose end in an investigation troubled him deeply.

“Certainly, I looked for it,” Chester replied, haughtily indignant. “I went through every room and closet and drawer in the house. But it’s completely disappeared. . . . Probably got thrown out by mistake in one of the annual house-cleanings.”

“That’s possible,” agreed Vance. “What sort of a revolver was it?”

“An old Smith & Wesson .32.” Chester appeared to be trying to refresh his memory. “Mother-of-pearl handle: some scroll-engraving on the barrel—I don’t recall exactly. I bought it fifteen years ago—maybe longer—when I went camping one summer in the Adirondacks. Used it for target practice. Then I got tired of it, and stuck it away in a drawer behind a lot of old cancelled checks.”

“Was it in good working order then?”
