"Then why was he here on the night of the murder?" "It was an accident. For some reason of his own, Dr. Binjoy, whom I met at Taxton-on-Thames, was in the habit of changing his name when in London. He usually stayed with Dr. Turnor, who is an old friend of his; and did his work when Turnor was absent. When I found out the murder, I sent for Dr. Turnor, he was away, and Dr. Binjoy came under his name of Renshaw. I was astonished to see him. I did not know that he was in town." "Oh! Had you any reason to go to Mere Hall to see him?" "Mere Hall!" stammered Mrs. Boazoph, "you saw me at Mere Hall?" "I saw you with my own eyes; you cannot deny that." "I have no wish to deny it," retorted Mrs. Boazoph, with asperity, "yes I was at Mere Hall. I went there to warn Binjoy against you." "Indeed; and no doubt Binjoy assured you that he had baffled me by the pretended journey to Bombay." "Yes, he said that." "And did he say that he had sent his negro, Caesar, to Bombay, in his place?" Mrs. Boazoph drew back and gasped, holding tightly on to the arms of her chair. "You know that?" she said, in alarm. "I know that, and a great deal more," said Fanks, grimly. "In fact, I more than suspect that I know the assassin." "Then you know that Caesar killed Sir Gregory?" "You jump to conclusions, Mrs. Boazoph," said Fanks, noting the tone of relief in which she made this remark. "I do not know that Caesar killed Sir Gregory Fellenger. But I know that both you and Dr. Binjoy would like me to think so." "Man! Man!" cried Mrs. Boazoph, with an hysterical laugh, "do you think that I had anything to do with this crime?" "Why not; the man was killed in your house: you called in a doctor, who is the dearest friend of the present baronet; it was to Binjoy's interest that Sir Gregory should be got out of the way." Again Mrs. Boazoph seemed relieved. "Then you suppose that Binjoy instructed Caesar to kill Sir Gregory?" "No, I do not; Caesar had nothing to do with the commission of the crime." "Then who was the black man who killed the baronet?" "It was no black man." "But it was," said. Mrs. Boazoph, angrily. "I saw him myself enter the room." "You saw a white man disguised as a negro enter the room." Mrs. Boazoph bounded to her feet. "What!" she cried, "do you mean to say that the black man was a disguised white man?" "Yes, I do say so; although I daresay it is no news to you." Mrs. Boazoph stamped her foot. "It is news to me, I tell you. I thought that Caesar killed Sir Gregory at the behest of Dr. Binjoy. When you entered the room I hoped to keep the fact from you; because I did not wish Binjoy to get into trouble. But you say that Caesar did not commit the crime, and so you have upset my ideas altogether. Now, Mr. Fanks, I tell you truly, that if this negro did not kill Sir Gregory, I do not know the name of the assassin."
