“Who’s the criminal, Zizi?” asked Wise. “The man who married Molly,” she returned, promptly. “Also the man who hunted and found the recipe. Molly saw him doing that, and made him marry her or she’d tell. If he could contrive a mock marriage of course he did. Or it may have been a real one. That doesn’t matter. It’s his identity that matters. Two men! That man, then, and another.” “Vail’s out of it,” Wise informed her, and told why. “Then, there’s Crippen,——” “No;” Zizi interrupted, “don’t go further afield. It’s—wait a minute,—get Bob Moore in here.” This was accomplished and Zizi did the interrogating. Care was taken not to divulge the new evidence and when Zizi asked him to detail his actions at the exact time of the crime, the man wonderingly recounted his oft-told tale. “Did Mr Vail seem about as usual when he was talking to you, going up in the elevator?” Zizi asked, casually. “Yes, but very chummy and talkative, more so than I ever knew him to be before.” “Yes? And did he detain you at this floor,—or did _you_ keep _him_, talking about the detective story you were reading?” “Why, I don’t know. Come to think of it,—I should say he detained me,—for he was so interested,—and, too, I never would have presumed to talk to him so familiarly if he hadn’t egged me on.” “Think back, now. Did he really keep you from going back by talking to you? Could you say he did that purposely?” “I can say that may have been the case,” Moore averred, thinking hard. “But he seemed really interested——” “As he never had been before,” commented Zizi, and adding, “and as he never has been since?” “No; he’s never been so chummy with me since. I’ve tried to talk to him about the Binney murder case, but he almost snubbed me,—at least he shut me off mighty quick.” “That’s all, Moore, and not a word to any one of anything that has been said in this room!” “Now,” said Zizi, after Moore had disappeared, “Vail’s one; who’s the other?” “Why, Zizi, Vail was in the elevator——” “Penny, I’ve known that ‘Vail was in the elevator’ all through this whole matter. I’ve been told a thousand times that Vail was in the elevator! It’s been fairly rubbed into my noddle that Vail was in the elevator! Why, don’t you see, that’s Vail’s alibi! His being in the elevator is his safeguard! Oh, Penny-poppy-show, sometimes I despair of _ever_ making a detective out of you! Well, my dear child, Mr Vail is one,—as I remarked,—and I found him; now you may find the other, and then we’ll have the ‘two men’ who ‘did this.’ Get busy.” “S’pose, since you’re so smart, _you_ find the other one,” said Wise, with no trace of jealousy in his tone. He was as elated at Zizi’s cleverness as if it had been his own, and he believed her implicitly. “I can do it,” she said, calmly. “Send for Molly.” “Yes, there’s the key to the situation,” Wise agreed.
