He went on at a quick pace, traversing block after block. He smiled ironically to himself, as he finally turned a corner, and with more caution now, approached a low frame building that was bordered by a dark and narrow lane. Yes, it was bizarre enough! He could not very well inform the police himself! The Rat—and particularly Billy Kane—was not at the moment on speaking terms with the police! But was it necessary to steal the diamonds?
Her idea, of course, was that then they would be absolutely safe from any attempt, or, perhaps what she feared most, physical coercion on the part of the Mole—even if Vetter were given a warning.
But surely Vetter could take care of himself if he were warned! He, Billy Kane, certainly preferred that method! But, even that, as an alternative, was not quite so simple as it appeared. He was still the Rat. He did not know the plan this so-called Mole had evolved, and, more vital still, he did not know how closely Red Vallon was, in turn, watching the Mole. It was eight o’clock now, and any or all of them might already be here. If he, Billy Kane, were discovered there would never be that little interview with Peters! The corollary was self-evident. Even for the purpose of warning the man, to reach Vetter inside this house here, that he was just passing, demanded the same degree of caution and secrecy on his part as though he entered for the purpose of stealing the stones himself. Also the little shop that made the front of the building was closed and dark. Vetter’s living quarters, he had heard, which was one of the eccentricities that had made the man a talked-of character on the East Side, consisted of no more than a single room, serving for every purpose, at the rear of the shop itself. He did not dare take the risk of inviting attention by rapping and bringing the old Hollander to the door.
He turned, and retracing his steps, sauntered nonchalantly along, passed by the house again—and slipped into the lane. Circumstances, as he found them, alone could govern his actions.
Billy Kane took stock now of the surroundings. The frame building was an old affair, and the floors therefore would be outrageously creaky. Billy Kane scowled. The prospect of creaky floors and protesting boards was not a pleasant one. And then the scowl vanished, and a smile flickered across his lips. From somewhere at the back of the house there came suddenly the throbbing notes of a violin. The smile broadened. That was Savnak, doubtless, and, for the moment at least, it was the violin, rather than pinochle, that was engaging the two men. Personally, under the circumstances, he, Billy Kane, was very much in favor of the violin. The violin would help a good deal—if it became a question of creaky floors!
