“I must know if you are right,” he cried, springing from his chair and beginning to pace the room. “I must know! How can I be sure, Inspector? You have found out so much; can’t you find out a little more?” “That’s what I came down for, Mr. Whymper,” French said gravely. “I must know too. And there’s only one way out of it. You’ve got to tell me the story. I’ll not use it unless it’s absolutely necessary. But I’ll test it and get to know definitely whether it’s fact or fiction.” Whymper paused irresolutely. “Suppose,” he said at length, “suppose, telling you the story involved letting you know of a crime which had been committed—not recently; many, many years ago. Suppose the criminal had escaped, but my story told you where you could find him. Would you give me your word of honour not to move in the matter?” French glanced at him sharply. “Of course not, Mr. Whymper. You know it is foolish of you to talk like that. Neither you nor I could have knowledge of that kind and remain silent. If you learn of a crime and shield the criminal, you become an accessory after the fact. You must know that.” “In that case,” Whymper answered, “I can’t tell you.” French became once more suave, even coaxing. “Now, Mr. Whymper, that is quite an impossible line for you to take up. Just consider your own position. I have ample evidence to justify me in arresting you for the theft of Mr. Averill’s money. If I do so, this story that you are trying to keep to yourself will come out: not privately to me, but in open court. Every one will know it then. By keeping silent now you will defeat the very object you are striving for. Attention will be forced on to the very person you are trying to shield. And when it comes out you will be charged as an accessory. On the other hand, if you tell me the whole thing here and in private you will ease your mind of a burden and may clear yourself of suspicion of the theft. And with regard to the other crime we may find that it is a pure invention and that no such thing ever took place. Now, Mr. Whymper, you’ve got to take the lesser risk. You’ve got to tell me. As I say, I’ll not use your evidence unless I must.” Whymper made no reply and French, recalling his theory that the secret concerned Ruth’s parentage, decided on a bluff. “Well,” he said, quite sharply for him. “If you won’t speak I shall have to get the information from Miss Averill. I shall be sorry to have to force her confidence about her parents, but you leave me no option.” The bluff worked better than French could have hoped. Whymper started forward with consternation on his face. “What?” he cried. “Then you know?” Then realising what he had said, he swore. “Confound you, Inspector, that was a caddish trick! But you won’t get any more out of me in spite of it.” French tried his bluff again.
