"Then you must not betray yourself," said Eustace, decidedly. "So far as looks go, he won't know you. I would defy even a detective to penetrate your disguise."

"Denham may twig me by my voice."

"I don't think from what I saw of him that he is so observant. Besides, I shall give you something to roughen your voice. You can say you have a cold."

Frank stared at his friend. "You seem to be up to all the tricks."

Jarman nodded. "I thought of being a detective myself once, and I practised for a time. I have all the materials for disguise here. I told you so when I made you up as Desmond O'Neil. I can get into the skin of a character with ease, and that's what you have to do. You are not Frank Lancaster, remember, but Desmond O'Neil from County Kerry."

"But, I say, Eustace, why do you want Denham down here?"

"Well, I wish him to report to the Berry lot that there is no concealment about me. They may suspect that I know something of your whereabouts, and I don't want either one to drop down upon me. Denham is a fool, and what he sees he will report to them in his artless fashion. Consequently, Berry and Fan will trust me. I want to get in with them and learn what they are up to."

"Do you think Denham can tell you?"

"No," said Eustace, promptly, "I don't. Whatever the game is, that boy is in the dark. He has much too loose a tongue for Berry to trust him with his secrets."

"But what's Berry bothering about him for?"
