Corcoran scratched his head in a puzzled manner.

“What’s all this got to do with finding the murderer?” he burst out.

Captain Dolan shook his head.

“There is no murderer,” he said.

We all looked startled, I imagine. Kenton would have spoken, but Captain Dolan motioned him to silence. Even Corcoran, for once, found himself without words.

“I spoke of an item in the paper tonight,” continued Captain Dolan. “Doubtless ’twas seen by all of you. Did you not read that one of the gorillas at the Zoo had escaped from its cage and was at large in the city?”

In the breathless silence which ensued I felt a peculiar thrill of terror pass up my spine. Kenton was fingering the holster of his revolver with nervous, clumsy motions. In some uncanny manner the gaunt old sea-captain’s grim words of doubtful import had woven about us all a web of superstitious fear in which we vainly struggled, unable to grasp the saving clew.

“’Twas that item which spoiled his supper for Terence, when he read it aboard the ship tonight. And no use I found it to reason with him. To his mind the grinning face of the big ape was peeping in at every porthole!”

Suddenly Corcoran whirled, peering into the blackness at the far end of the warehouse, where something stirred softly. Kenton drew his pistol. I felt the goose-flesh rising along my arms. Only the dead man, undisturbed, stared unwinkingly in the opposite direction.

The next moment a stray cat wandered leisurely into the circle of light and sat herself down to wash her dusty fur, blinking complacently up at our pallid faces. I wiped the cold drops from my forehead and breathed a deep sigh.
