Slowly and cautiously we made our way through the dark rooms, searching before us with the flash light. I can't speak for Arthur, but my breath was coming quickly, and I heartily regretted having expressed a wish for a drink. I would not back out now, though. We went cautiously and slowly out to the rear of the house. I was in the act of reaching for the siphon of seltzer when we heard the dog scream in pain and a shout from Evan. We rushed madly for the front, our hearts in our mouths, and cursing our absence at such a critical time. When we burst into the room, Evan was dashing out on the veranda, and Alicia was in the act of emerging from the room into which she and Mrs. Braymore had retired. Alicia had an automatic in her hand and, though her face was full of dread, she was evidently prepared to face anything. Arthur and myself were quickly by Evan's side and found him staring about the darkness, his rifle half raised. "What is it?" Arthur demanded quickly. Evan's breath was coming in gasps. "I heard you two moving," he said sharply, as one whose nerves are strained to the breaking point. "I heard a noise from your direction. I turned to look at the door and caught a movement at the window by my side. I jerked back and the dog screamed. A long, hairy arm had reached in the window and seized him. He was drawn through the window before I could lift my rifle, and the arm vanished. It's the gorilla!" We listened, but the house was still. A faint moan came from the courtyard, and I flashed the lamp down. The dog, flung bodily from the porch, stirred feebly and stiffened. Its neck was broken. There on the shadowed veranda, with the bright African moon shining pitilessly down upon the hot, dank, fevered earth, the three of us swore nervously while we stood with our rifles pointing in as many directions, hoping, even praying for that monstrous ape to rush upon us. "He must have gone somewhere!" said Arthur despairingly. "Where _did_ the beast go?" "Into the house, no," said Evan crisply. "Under the house, perhaps. The roof, perhaps. We'll see." My legs crawled as I descended the stairs to the ground. The house was raised from the ground on piles, and I could look clear underneath it. The moon was shining down whitely, and I saw the pillars silhouetted against the brightness on the other side. Half a dozen steps convinced me that the animal was not beneath. It would have shown as a dark outline. I tried to see up, over the roof, but could not. The roof slanted just a little and I could not see the center. The house being on an elevation, moreover, prevented me from backing off and getting a clear view of the top. I called up to the other two on the porch. "He's not under the house, but I can't see the roof. He must be there."
