"Same here, Garth. Depend upon it this murder is no bungling affair. It is a cleverly-planned and cleverly-executed scheme; carried out by people who know what they are doing. As the case now stands I cannot see my way. The evidence--in my opinion--leads to nothing. If Crate had this matter in hand he would arrest Binjoy on suspicion, and hunt for the negro servant as the supposed murderer, and by doing so he would make a mess of the whole business. I shall arrest nobody--at present. Save to yourself and perhaps Crate I shall give my opinions to nobody. I shall watch and wait; put two and two together, and when they make four I shall pounce on the assassin. It will take time and patience and money, but, as I said before, the case is a delicate one. We are dealing with people who are as clever and cleverer than we are. I confess that the outlook is anything but promising," concluded Fanks, with a sigh. "You cannot guess who committed the crime?" "No, I cannot. To all appearances it was the negro, but--and this is the main point--was it the negro of Binjoy, and would the negro be clever enough to conceive so subtle a method of committing a crime as the mode of the poisoned needle? Again, would a negro be in possessiondied of such information as would induce Fellenger to permit the use of the needle? The whole mystery lies in that cross tattooed on the arm. When I discover its meaning I shall be able to name the assassin." "Then why not see Hersham?" suggested Garth. "He has a similar tattoo mark on his left arm. He may be able to tell you what you wish to know." "I have an appointment with Hersham at his rooms to-morrow. I may learn something from him; on the other hand, I may learn nothing." "And what about Emma Calvert?" "Oh, I shall find out about her at Taxton-on-Thames. I may discover dead Lady Fellenger of Paris alive at the Surrey village under another name. And yet," added Fanks, producing a paper, "Crate's report proves that the woman died in Paris in 1893, and was buried in Pere la Chaise." "If that is so, who was the woman who appeared so strangely? The evidence of the photograph and the valet both prove that she is Emma Calvert." "I can only surmise that she did not die; but that either knowingly or unknowingly some woman was buried in her place. It is the only explanation that I can give. Yet, for all I know, Emma Calvert may have employed that negro to kill her wicked husband." "It is a wild theory," said Garth, "why should this woman, the lawful wife of my cousin, pretend to be dead, and submit to have her identity destroyed by the false burial? If she is alive, I can quite conceive that she should have my cousin killed out of revenge; but why the pretended death, which--to all appearances--was acquiesced in by Fellenger?" "I can't answer that question until I wring the truth from Robert." "There is no necessity for Robert. I have found another person who can tell you the truth."
