"It was now six o'clock. His appointment with Mrs. Weston in Forston Street was fixed for eight. He had an hour and a half to spare, sufficient time to take a chop and a pancake and to arrange his ideas. Selecting a quiet-looking restaurant, he took a seat at an unoccupied table, ordered his chop and pancake, and began to write in the convenient reporter's book which he always kept about him. He did this for clearness; he felt that he was approaching an important point in the mission he had taken upon himself, and that his interview with Mrs. Weston was destined to be pregnant in results. It would be of assistance to him to set things down in writing instead of trusting entirely to memory. The memoranda he made are now set forth: "Heads of circumstantial evidence which lead me to the belief that Mrs. Mary Weston, otherwise E. B. (initials worked in lady's handkerchief), is directly connected with the incidents which happened in Mrs. Middlemore's house in Gerard Street, Soho, on the night of the death of M. Felix. "First--On that night a man was seen making a hurried escape from the house at the moment (presumably) M. Felix was drawing his last breath. The only description, if description it can be called, that has been given of this man is that he wore round his neck a red scarf. "Second--Last night, or rather early this morning, on the occasion of my visit to Mrs. Weston's lovely daughter, I observed, before I left the young lady, a red silk scarf. Query: Might not this red scarf be the same as that which the man who escaped from the house in Gerard Street wore round his neck? "Third--There was blood on the floor of M. Felix's room. There was no wound on the body of M. Felix. The blood, therefore, proceeded from a wound inflicted on the person of M. Felix's visitor. My discovery in M. Felix's room of the dagger, with a handle resembling a twisted snake and a ruby in its head to represent an eye, led to the incontrovertible conclusion that it was the weapon with which this wound was inflicted. The blood stains on the blade prove it. M. Felix, snatching up the dagger, flung it at his visitor. "Fourth--Mrs. Weston has on her left arm a wound which is not yet healed. When I inadvertently grasped her arm she cried from pain. Inquiring whether I had hurt her she replied that her arm had 'been cut to the bone.' Query: Might not this be the wound that was inflicted by M. Felix's dagger? "Fifth--In that case Mrs. Weston must have paid a visit to M. Felix on the night of his death. Query: Might she not have paid this visit disguised in a man's clothes?
