"Thanks. I don't fancy you need be under any apprehension that anybody has spirited Van Sneck away. In the first place Henson, who seems to have discovered what happened, is in a terrible state about it. He wanted very badly to remain at Littimer, but when he heard that Van Sneck had left the hospital he came down here; in fact, we travelled together. Of course he said nothing whatever about Van Sneck, whom he is supposed to know nothing about, but I could see that he was terribly disturbed. The worst of it is that Cross was going to get me to operate on Van Sneck; and Heritage, who seems wonderfully better, was going to assist."

"Is your unfortunate friend up to that kind of thing now?" David asked.

"I fancy so. Do you know that Heritage used to have a fairly good practice near Littimer Castle? Lord Littimer knows him well. I want Heritage to come into this. I want to get at the reason why Henson has been so confoundedly good to Heritage. For years he has kept his eye upon him; for years he has practically provided him with a home at Palmer's. And when Heritage mentions Henson's name he always does so with a kind of forced gratitude."

"You think that Heritage is going to be useful to us?"

"I fancy so. Mind you, it is only my idea—what I call intuition, for want of a better word. And what have you been doing lately?"

David proceeded to explain, giving the events of the afternoon in full detail. Bell followed the account with the deepest interest. Then he proceeded to tell his own story. David appeared to be fascinated with the tale of the man with the thumb-nail.

"So Miss Chris hopes to hypnotise the man with the thumb," he said. "You have seen more of her than I have, Bell. Does she strike you as she strikes me—a girl of wonderfully acute mind allied to a pluck and audacity absolutely brilliant?"

"She is that and more," Bell said, warmly. "Now that she is free to act she has developed wonderfully. Look how cleverly she worked out that Rembrandt business, how utterly she puzzled Henson, and how she helped me to get into Littimer's good books again without Henson even guessing at the reason. And now she has forced the confidence of that rascal Merritt. She has saved him from a gaol into which she might have thrown him at any moment, she has convinced him that she is something exceedingly brilliant in the way of an adventuress, with a great coup ahead. Later on she will use Merritt, and a fine hard-cutting tool she will find him."

"Where is Henson at the present moment?" David asked.

"I left him in London this afternoon," Bell replied. "But I haven't the slightest doubt in the world that he has made his way to Brighton by this time. In all probability he has gone to Longdean."
