Fanks bowed, and there was a silence between them for a few moments. He glanced round the neatly furnished room; at the pictures and photographs; but among them all he could not see one of the dead Emma. At the elbow of Mrs. Colmer, on a small table, stood a pile of photographs, at which she had evidently been looking prior to his entrance, and Fanks surmised that a portrait of Emma might be there. He was anxious to discover one, if possible, as Anne had denied that there was a photograph of her sister in existence save the one which she had sought at Sir Gregory's chambers. Fanks thought that if he could find another in the pile at Mrs. Colmer's elbow he would be able to convict Anne out of her own mouth, and expose the falsity of the motive she gave for her visit. He cast about for some means whereby to accomplish his purpose. "You will excuse me, Mrs. Colmer," he said, rising from his seat, "but that is an excellent picture of the Bay of Naples." He had crossed over to the other side of the room to look at the picture, and so found himself standing by the small table which held the sundry pictures. In turning away he pretended to stumble, and so knocked over the table and photographs. "Thousand apologies," said Fanks, in confusion, stooping to pick them up. He looked in vain for the face he sought; but he made a discovery which startled him not a little. The last photograph which he picked up off the carpet was one of--Mrs. Boazoph. CHAPTER XIX. THE DEFIANCE OF ANNE COLMER. Before Fanks could remark on the strangeness of this discovery, the door opened and Anne entered the room. With characteristic quickness she recognised the photograph in the hand of the detective. At once she came forward, and signed to him to be silent. At the same time she spoke to her mother. "Mr. Fanks has been shown into this room by mistake," she said, hurriedly; "so with your permission, mother, I shall conduct him into the next room." "As you please, Anne; you know best." Accepting this permission Anne drew Fanks quickly into the passage, and led him into the apartment he had seen on the occasion of his last visit. He still held the photograph in his hand; and at this she looked anxiously as she signed to him that he should take a seat. Fanks placed himself in a comfortable armchair; Miss Colmer took up her position opposite to him, and both prepared for a difficult conversation. As was natural from her late action, she made an observation on the picture of Mrs. Boazoph. "I see that you recognise that face," said Anne, coolly; "no doubt you wonder how that photograph came to be in this house?" "I do wonder. Am I to hear the truth from you, Miss Colmer?" "Certainly; there is no reason why I should tell you a lie." Man and woman looked directly into one another's eyes, and a look of mutual distrust passed between them. It was Fanks who first took up the unspoken challenge.
