With becoming modesty, but a good deal of emphasis, Crate asserted that he did, and moreover said that if permitted by his superior officer he would have great pleasure in proving his case against the barrister. To this Fanks assented readily enough. "Prove your case by all means, Crate," he said, dryly. "I do not agree with you in the least; all the same I am always open to correction. One thing only I ask. You must tell me all you do, all you discover, as I do not wish you to cross my trail." This Crate assented to without demur, and Fanks departed to Duke Street, where he changed his clothes for the more stylish ones of Rixton. Thence he went to the Athenian Club, and, as he expected, found Garth in the smoking-room. The lean lawyer looked so haggard and worn out that Fanks wondered if there might not be more in Crate's theory than appeared at first sight. But he rejected this idea almost as soon as it crossed his mind; he was confident that the true assassin of Sir Gregory was--but that revelation comes later. In the meantime he greeted Garth with his customary coolness, and sat down beside him with a view to learning all that had transpired during his absence. "Were you waiting for me here?" he asked, lighting a cigarette. "Not exactly," replied Garth, with some hesitation. "I hoped that you would come in here sooner or later, and I wished to see you. But at present I am waiting for Herbert Vaud." "Really! Do you expect him shortly?" Garth looked at his watch. "He ought to be here now." "What do you wish to see him about?" asked Fanks, eyeing his companion keenly; "anything about this case?" Garth nodded. "Yes; young Vaud knew Emma Calvert, and I wish to learn if she is really dead." "You can set your mind at rest on that point," said Fanks, coolly. "Emma Calvert is six feet below the soil of Pere la Chaise." "But the woman who appeared at my cousin's chambers; the woman whom Robert said was she." "That is Anne Colmer, the twin sister of the dead woman." "Anne Colmer! She is engaged to Ted Hersham." "She is. I have been down to Taxton-on-Thames, and I have found out all the family history." "Have you found out who wrote on the back of the photograph; who directed that envelope?" "No," said Fanks, gloomily, "I have not discovered anything yet about that." "Do you think that Anne Colmer wrote it?" "I am certain from personal observation that Anne Colmer did not." "Did her mother?" "Impossible. Mrs. Colmer is a hopeless paralytic." "Then who wrote it?" "That is just what I have to learn. I am no further in the case than I was when I saw you last. Have you discovered anything?" "No; but I had hoped to have learned about Emma from Herbert." "Well," said Fanks, with a sigh, "we know all about Herbert Vaud; we are aware of the identity of Emma Calvert. It is not in that direction we must search. Our only chance of finding out the truth, lies in discovering this negro."
