"Rats!" exclaimed Peter, feelingly. "Quit your kiddin', O'Malley. Don't joke. This is serious. Both these women are missing, and there's blood in the apartment and on Miss Blake's scarf. We only know how one of 'em left the place. She left alone ... with a big trunk.... It was a big trunk, O'Malley. I could tell by the marks it had made on the wall of the storeroom, and by the place where there wasn't any dust at all on the floor. It was all pretty clean, but you just could see where the trunk had stood.... And then, here's another funny thing--the closets in the bedroom were all full of beautiful clothes, the sort you'd expect Mary Blake to wear, and the bureau was, or had been, full of fine, expensive lingerie, before somebody chucked 'em around the place. Now, I figure Anne kept her clothes in the storeroom--and there wasn't a rag there--nothing but a few almost worn-out things in an otherwise empty chiffonier." "And you argue from that----" said O'Malley. "I'm not arguing," said Peter. "I'm only thinking. It looked to me as if Anne had taken all her clothes (though there probably weren't so many, judging by the number of hangers and the size of the chiffonier) and that Mary hadn't taken anything.... Of course it's only a guess. I can't be sure. But that's the way it looked.... And how would Mary get along without clothes--unless she might have been going to use Anne's?... But they didn't go away together.... Morris has the idea--and I got it myself from the letter he showed me--that there was a sort of--a kind of antipathy between them. Oh, hell, O'Malley! You see what I'm driving at--I've been mixed up with so much crime and stuff that I can't help wondering----" "Yes," said O'Malley, slowly. "Yes, I see.... The bloody scarf that the cabby pulled through the door ... the blood on the floor of the hall just by the trunk-room ... the big trunk.... H'm'm----" The two detectives looked at each other long and seriously. Then Clancy brought his closed fist down on the desk. "It's Anne--it's Anne I want to find, O'Malley! We'll look for Mary for all we're worth. We won't leave a stone unturned, as I promised. But if you ask me what we must do to get to the bottom of this proposition, I say--find Anne Blake!" CHAPTER XI FOUR PHOTOGRAPHS "Yes. Find Anne Blake," O'Malley repeated, slowly. "But, in the meantime, son, you'd have to establish a motive, and it'd have to be some little motive, at that! And after all, you know, Miss Mary may turn up at any time. It would be easy enough for her to make a get-away and nobody see her. Suppose she slipped quietly out into the street and picked up a cab on the Avenue or somewhere? How'd we find that cab, I ask you? We don't know where she was going, and there wouldn't be anything to spot her by but a description or a photograph, if you can get hold of one."
