He ascended the stairs of the "L" station, on the near side, and paying a nickel passed through a turnstile onto the platform. Waiting until just after a train had left, and the long, windy sweep of planking was solitary, he dropped onto the narrow footway that runs beside the track. This required watchful walking, for the charged third rail was very near, but hugging the outer side of the path he proceeded without trouble. Every fifteen feet or so a girder ran sideways from the track, resting upon an upright from the street below. The fourth of these overhung the back corner of Weintraub's house, and he crawled cautiously along it. People were passing on the pavement underneath, and he greatly feared being discovered. But he reached the end of the beam without mishap. From here a drop of about twelve feet would bring him onto Weintraub's back roof. For a moment he reflected that, once down there, it would be impossible to return the same way. However, he decided to risk it. Where he was, with his legs swinging astride the girder, he was in serious danger of attracting attention. He would have given a great deal, just then, to have his overcoat with him, for by lowering it first he could have jumped onto it and muffled the noise of his fall. He took off his coat and carefully dropped it on the corner of the roof. Then cannily waiting until a train passed overhead, drowning all other sounds with its roar, he lowered himself as far as he could hang by his hands, and let go. For some minutes he lay prone on the tin roof, and during that time a number of distressing ideas occurred to him. If he really expected to get into Weintraub's house, why had he not laid his plans more carefully? Why (for instance) had he not made some attempt to find out how many there were in the household? Why had he not arranged with one of his friends to call Weintraub to the telephone at a given moment, so that he could be more sure of making an entry unnoticed? And what did he expect to see or do if he got inside the house? He found no answer to any of these questions. It was unpleasantly cold, and he was glad to slip his coat on again. The small revolver was still in his hip pocket. Another thought occurred to him--that he should have provided himself with tennis shoes. However, it was some comfort to know that rubber heels of a nationally advertised brand were under him. He crawled quietly up to the sill of one of the windows. It was closed, and the room inside was dark. A blind was pulled most of the way down, leaving a gap of about four inches. Peeping cautiously over the sill, he could see farther inside the house a brightly lit door and a passageway.
