"Then he told you, sir, that he had found Salter?"
"No, he did not. We were speaking on supposition."
"Who is this gentleman, sir?"
"I don't know who he is. He keeps his name from me."
Mr. Grimley felt anything but satisfied with the present aspect of the affair. What right had this stranger, who wanted to know all about Salter, to refuse to denounce him? Once more he asked Mr. Burtenshaw if he did not know who he was, but the latter repeated his denial. During the discussion, the man Watts entered the room again, and heard what passed. He looked at Mr. Burtenshaw.
"Are you speaking of the gentleman just gone out, sir? I know him."
"Why, who is he?" asked Mr. Burtenshaw, who had taken out the little box again, and was opening it.
"Sir Karl Andinnian."
"Nonsense!" exclaimed the detective, aroused to interest. For Sir Karl Andinnian, brother to the criminal who had made so much stir in the world, was a noted name amongst the force.
"It is," said Watts. "I knew him the minute I came in. I was present at the trial in Northampton, sir, when his brother was condemned to death; this gentleman sat all day at the solicitors' table. I had gone down there on that business of Patteson's."
