Rhoda Gray's lips tightened a little, as she hurried along. Old Nicky Viner still lived in the same disreputable tenement in which he had lived on the night of that murder two years ago, and she could not ward off the thought that it had been--yes, and was--an ideal place for a murder, from the murderer's standpoint! The neighborhood was one of the toughest in New York, and the tenement itself was frankly nothing more than a den of crooks. True, she had visited there more than once, had visited Nicky Viner there; but she had gone there then as the White Moll, to whom even the most abandoned would have touched his cap. To-night it was very different--she went there as a woman. And yet, after all--she amended her own thoughts, smiling a little seriously--surely she could disclose herself as the White Moll there again to-night if the actual necessity arose, for surely crooks, pokegetters, shillabers and lags though they were, and though the place teemed with the dregs of the underworld, no one of them, even for the reward that might be offered, would inform against her to the police! And yet--again the mental pendulum swung the other way--she was not so confident of that as she would like to be. In a general way there could be no question but that she could count on the loyalty of those who lived there; but there were always those upon whom one could never count, those who were dead to all sense of loyalty, and alive only to selfish gain and interest--a human trait that, all too unfortunately, was not confined to those alone who lived in that shadowland outside the law. Her face, beneath the thick veil, relaxed a little. Well, she certainly did not intend to make a test case of it and disclose herself there as the White Moll, if she could help it! She would enter the tenement unnoticed if she could, and make her way to Nicky Viner's two miserable rooms on the second floor as secretively as she could. And, knowing the place as she did, she was quite satisfied that, if she were careful enough and cautious enough, she could both enter and leave without being seen by any one except, of course, Nicky Viner.
