closed it behind him with equal caution, and, in the dark entry, stood motionless, listening intently.
There was no sound. He began to mount the rickety, dilapidated stairs; and, where it seemed that the lightest tread must make them creak out in blatant protest, his trained muscles, delicately compensating his body weight, carried him upward with a silence that was almost uncanny. There was need of silence, as there was need of haste. He was not so sure now of the time at his disposal—that he had even reached the Sanctuary first. How long had he loitered in that half-dazed way on the Bowery? He did not know—perhaps longer than he had imagined. There was the possibility that Whitey Mack and Lannigan were already above, waiting for him; but, even if they were not already there and he got away before they came, it was imperative that no one should know that Larry the Bat had come and gone.
He reached the landing, and paused again, his right hand, with a vicious muzzle of his automatic peeping now from between his fingers, thrown a little forward.

There was no light. He dared not use the gas; it might be seen from the alleyway. He was moving now quickly, surely, silently here and there. It was like some weird spectre figure, a little blacker than the surrounding darkness,
