In another three seconds he was flat on the bedroom floor, shooting the light along the under side of the bed. He saw a series of squares of rope, upholding the thick corn-husk mattress. Within each square the mattress bellied downward. And in one of those rounded curves of cloth, near the outer edge of the bed, opened a hole.

Douglas lay there, staring up at that hole, until his position grew cramped. It was round and smooth-edged; the edges looked worn, as if something had often passed in and out—something scaly, perhaps, whose passage would wear away loose threads. The sagging cloth hung not more than a foot above the floor. And, now that his nose was near it, he became conscious of a repellent odor—a smell suggesting snakiness.

“Ugh!” He scrambled to his feet and took a breath of clean air. His gaze fell on the rent left in the middle of the bed by Nigger Nat’s steel. Swift aversion to the whole room seized him. He spun about and stepped out of it. And as he left it he did something he never had done before—he pulled its creaky door shut behind him. He was through with that loathsome death-chamber for all time.

The dead snake now was almost motionless: only the blunt tail still quivered in reptilian tremors. Giving it only a passing glance, Douglas stopped before the open staircase and swung the light slowly from side to side, examining every step. When the all-revealing radiance was centered on the top he stood as if puzzled. Down to the bottom and up to the top he played it again.

“H’m! How come?” he queried.

The darkness gave no answer. Only the solemn crickets dirged on outside.

Up the echoing stairs he clumped, and on the groaning boards above he deliberately moved about, searching the dusty, dusky recesses of the eaves. Presently the moving light stopped, shining steadily into one of the front corners. Through the dingy cobwebs festooning the nook he saw something which brought a satisfied nod.

“One,” he said. With that he turned away and began descending the stairs.

Almost at the bottom, he halted short. The downward-pointing ray had revealed a thing hitherto invisible despite his careful scrutiny of the stairs; something which an up-ranging eye never would see, and which was discernible from above only because the swaying light had happened to strike on it.

“Two!” he exulted. “That’s it! I’ve got the combination now. Farewell, Mister Ha’nt! Your little mystery is busted flat.”
