He had sent a woman detective to interview the matron of the women's waiting room in the Pennsylvania Station. This detective found that the neat coloured woman, in charge of the pay dressing rooms, remembered seeing a veiled lady come in there on Sunday evening. She couldn't be sure, but she thought it was after five. It was not very long before the time when she went off duty, and that was at six. She recollected, too, that the lady had some sort of disfigurement on her face. She had received the fee and opened one of the pay dressing rooms for her, but whether it was because the lady stayed in there till after her time was up, or for whatever reason, the coloured woman had no recollection of seeing her again. And after three weeks of almost incessant toil this was the one thing Peter had learned. Porters and conductors of every train which left the Pennsylvania Station on that fateful Sunday night had been personally interviewed. Not one remembered seeing any such lady as Peter described. As far as he was able to learn, Anne Blake might have vanished into thin air. The search for a cab which Mary Blake might have taken on that Sunday evening had proved equally fruitless. The city, as Peter had promised Donald Morris, had been gone over with a fine-tooth comb. All the big taxi companies, the smaller garages, and all the "free lances," from the Bronx to the Battery, had been investigated, to no purpose. No one had seen Mary Blake leave Waverly Place and every trace of her was utterly lost. Like her sister, she had slipped out of sight, leaving no ripple to betray her passage. "It looks as if the only chance of getting results would be to let the story leak out to the papers," said Peter to O'Malley, late one afternoon toward the end of June. "Mr. Morris is dead against it. Thinks that Miss Mary would hate the publicity worse than anything in the world. And even if we could persuade him to let us go ahead and practically advertise, even then I'm not any too hopeful." He sighed, wearily. "I don't see, in any case, why Anne should come out of the woods. Dammit! If she'd only draw some of that money that's lying up there at the Scoville Bank, it might give us a look-in. But they haven't heard a word. I'm sure she's got plenty of funds in hand, all right, and is lying low. Wonder how she figures to pull out that money without any one getting wise as to where she is." "I've been puzzling about that, too," said O'Malley. "Seems as if she'd have to take somebody into her confidence to put it across, but if what we've doped out is true, and Mary Blake never turns up, for the simple reason that----" He made an expressive gesture.
