"But Skinner—the butler—recognised him?"
"Exactly. It goes to prove that what I said about Skinner was correct. They are working together. The thing is self-evident. Look at it from your point of view. How simple it is. This man pretends to an intimate acquaintance with Skinner. You take that as evidence of Skinner's honesty. Skinner recognises this man. You take that as proof that this man is really your nephew. The fact that Skinner recognised as Jimmy Crocker a man who is not Jimmy Crocker condemns him."
"But why did you—?"
"I told you that I pretended to accept this man as the real Jimmy Crocker for a purpose. At present there is nothing that you can do. Mere impersonation is not a crime. If I had exposed him when we met, you would have gained nothing beyond driving him from the house. Whereas, if we wait, if we pretend to suspect nothing, we shall undoubtedly catch him red-handed in an attempt on your nephew's invention."
"You are sure that that is why he has come?"
"What other reason could he have?"
"I thought he might be trying to kidnap Ogden."
Lord Wisbeach frowned thoughtfully. He had not taken this consideration into account.
"It is possible," he said. "There have been several attempts made, have there not, to kidnap your son?"
"At one time," said Mrs. Pett proudly, "there was not a child in America who had to be more closely guarded. Why, the kidnappers had a special nick-name for Oggie. They called him the Little Nugget."
