"Do you think she knows that?"
"I think she has known it all along," retorted Fanks. "You can take it from me, Fellenger, she recognised the negro when he entered the hotel on that night. For some reason, which I mean to discover, she has held her tongue. I intend to force her to reveal the name by threatening to arrest Hersham, in the event of her refusing to speak."
"Will she tell in order to save Hersham?"
"I think so; and for more reasons than one. You see she fainted when I told her that I could prove the crime against that young man. It may be that she knows how hardly he has been dealt with by Madeline Garry, and therefore she may be anxious to save him further trouble."
"But how could she learn the story of Madeline Garry and the changing of the children," objected Fellenger.
"From Anne Colmer, who must have learned it from Dr. Binjoy. I believe he is at the bottom of the whole affair. I do not say that he killed Gregory; but he can tell us who did."
"How can you prove that?"
"Well, the person who killed Gregory must have known that story of the changing of the children, so as to induce him to let the cross be tattooed on his arm. Dr. Binjoy must have told that person; Dr. Binjoy must have supplied that needle; Dr. Binjoy, my friend, is at the bottom of the whole devilish affair."
"You forget Madeline Garry; she might have told the murderer about the changing of the children."
"I don't think so. Madeline would not have been likely to reveal anything detrimental to her son; and on the face of it she could not have obtained access to the poisoned needle. No, I suspect Binjoy as an accessory before the fact. I shall see Mrs. Jerusalem, and force her to tell me where to find Madeline Garry; though to be sure I have a pretty good notion of where to find her as it is."
