"Yes, that's all. Well, what do you make of it?"
"I'm afraid I don't quite see the connection with this case."
"Well, then, I'll give you another point. The telegram I've just sent releases information to the police, in consequence of which they will probably apprehend Harvey Challitt and his confederate, Henry Gillard, alias Jones, for the murder of Gavin Kingscote. Now, then."
"Challitt! But he's in gaol already."
"Tut, tut, consider. Five years' penal was his dose, although for the first offence, because the forgery was of an extremely dangerous sort. You left Chelsea over three years ago yourself, and you told me that his difficulty occurred a year before. That makes four years, at least. Good conduct in prison brings a man out of a five years' sentence in that time or a little less, and, as a matter of fact, Challitt was released rather more than a week ago."
"Still, I'm afraid I don't see what you are driving at."
"Whose story is this about the diamond robbery from Harvey Challitt?"
"His own."
"Exactly. His own. Does his subsequent record make him look like a person whose stories are to be accepted without doubt or question?"
