"'Ain't going to be done in the dark same as what Joe's been,' the other whispered sulkily. 'If anyone comes down 'ere, I pots 'im.'

"At this moment there was another very audible creak from above, and then followed rapidly a succession of events which I subsequently disentangled, but which, at the time, were involved in utter confusion. What actually happened was that Fred had begun boldly to ascend the stairs, in some way missing the fishing-line, and being closely followed by his more nervous comrade. The latter, less fortunate, caught his foot in the line, stumbled, tightened the line and brought the shot-bag hopping down the stairs. What I heard was the sound of the stumble, followed by the quick thud, thud, of the descending shot-bag, exactly resembling the footfalls of a heavy man running down the stairs barefoot. Then came two revolver shots in quick succession, a shower of plaster, a hoarse cry, a heavy fall, and, from above, a loud scuffling followed by the slamming of a door and the noisy turning of a key; a brief interval of silence and then a quavering whisper.

"'I ain't 'it yer, Fred, 'ave I?'

"To this question there was no answer but a gurgling groan. I stepped out from my hiding-place, passed through the open doorway and stole softly along the hall, guided by the sound of the survivor extricating himself from his fallen comrade. A few paces from him I halted with the concussor poised ready to strike and listened to his fumbling and scuffling. Suddenly a bright light burst forth. He had found Fred's electric lantern, which was, oddly enough, uninjured by the fall (it had a metal filament, as I subsequently ascertained).

"The circle of light from the bulls-eye, quivering with the tremor of the hand which held the lantern, embraced the figure of the injured burglar, huddled in a heap at the foot of the stairs and still twitching at intervals. It could not have been a pleasant sight to his companion. The greenish-white face with its staring eyes and blood-stained lips stood out in the bright light from its background of black darkness with the vivid intensity of some ghastly wax-work.

"The surviving burglar stood petrified, stooping over his comrade, with the lantern in one shaking hand and the revolver still grasped in the other; and as he stood, he poured out, in a curious, whimpering undertone, an unending torrent of incoherent blasphemies, as appears to be the habit of that type of man when frightened. I stepped silently behind him and looked over his shoulder at the expiring criminal, speculating on what he would do next. At the moment he was paralyzed and imbecile with terror, and I had a strong inclination to dispatch him then and there; but the same odd impulse that I had noticed on the last occasion constrained me to dally with him. Again I was possessed by a strange, savage playfulness like that which impels a cat or leopard to toy daintily and tenderly with its prey for a while before the final scrunch.

"We remained thus motionless for more than half a minute in a silence broken only by his blasphemous mutterings. Then, quite suddenly, he stood up and began to flash his lantern on the stairs and about the hall until at length its light fell full on my face which was within a foot of his own. And at that apparition he uttered a most singular cry, like that of a young goat, and started back. Another moment and he would have raised his pistol arm, but I had foreseen this and was beforehand with him. Even as his hand rose, the concussor struck the outer side of his arm, between the shoulder and the elbow, on the exact spot where the musculo-spiral nerve turns round the bone. The effect was most interesting. The sudden nerve stimulus produced an equally sudden contraction of the extensors. The forearm straightened with a jerk, the fingers shot out straight and the released revolver flew clattering along the hall floor.

"Anatomy has its uses even in a midnight scuffle.

"The suddenness of my appearance and the promptness of my action paralyzed him completely. He stared at me in abject terror and gibbered inarticulately. Only for a few moments, however. Then he turned and darted towards the street door.

"But I did not mean to let him escape. In a twinkling I was after him and had him by the collar. He uttered a savage snarl and dropped the lamp on the mat to free his hands; and, as the spring switch was released, the light went out, leaving us in total darkness. Now that he was at bay, he struggled furiously, and I could hear him snorting and cursing as he wriggled in my grasp. I had to drop the concussor that I might hold him with both hands, and it was well that I did, for he suddenly got one hand free and struck. It was a vicious blow and had it not been partly stopped by my elbow the adventure would have ended very differently, for I felt the point of a knife sweep across my chest, ripping open my pajama jacket and making a quite unpleasant little flesh-wound. On this I gripped him round the chest, pinioning both his arms as well as I could and trying to get possession of the knife, while he made frantic struggles to aim another blow.
