“That is true,” Nick agreed. “Have you ever seen David Margate or heard anything concerning him since he was convicted in London?” “No, I have not.” “You have no reason to believe that he is in New York, then, aside from the resemblance of the criminal who committed this jewel robbery.” “That is my only reason. You now can appreciate why I was overcome and fainted when told of the circumstances this morning,” said Mrs. Clayton. “That is perfectly plain,” Nick nodded. “I think, too, that we now have covered all of the ground that is material at this time. I will be governed by what you have confided to me, and will do all that I can to prevent the facts from leaking out. You may depend upon that.” “I have no words with which to thank you, Mr. Carter.” “Don’t try,” said Nick, smiling. “Assuming that the criminal in this case is Chester’s twin brother, and despite that he ran across him and observed the resemblance that made the crime possible, I think it is quite probable that he does not suspect the relationship. Your husband very likely never told him about you and Chester.” “Do you really think so, Mr. Carter?” “I do,” said Nick. “Men do not often reveal their own baseness, not even to a son. I doubt very much that David Margate knows anything about his early history.” “I hope so, I am sure, for Chester’s sake.” “Do you know under what name he was convicted in London?” “I do not. I cannot recall it.” “Was it a fictitious name?” “Yes.” “I will try to learn something definite about him,” said Nick. “I appreciate your confidence in me, too, and I will rigidly respect it. That is all I can say to you this evening about the case, but I will leave no stone unturned to bring it to a desirable termination, particularly in so far as you and Chester Clayton are concerned.” Mrs. Clayton again thanked him feelingly, then remarked: “I was somewhat surprised late this afternoon by a call from another man whom I saw in Mademoiselle Falloni’s suite this morning.” “There was only one other man, except Chester,” said Nick. “You refer to Doctor Guelpa.” “Yes.” “He called here to see you?” “Yes, about five o’clock.” “Did he say for what reason?” “He said that he was riding out this way and thought he would call and see if I had entirely recovered. He did all he could to revive me this morning, you know.” Nick’s brows knit a little closer. “Yes, I remember,” he replied. “Did he say anything about the crime, or concerning Clayton?” “No, nothing of any consequence, Mr. Carter. He mentioned you, however, just before he left.” “Mentioned me, eh? What did he say?” “Only that you were very kind to stand up for Clayton under such circumstances. He asked, too, whether you had been out here to see me.”
