"Yes, yes, I see," Sir Houston replied dubiously. "If there were any traces of foul play I should at once be of the same opinion. But you see they do not exist." "Whether there are traces, or whether there are none, nothing will shake my firm opinion, and that is that poor Jerome has been assassinated, and the motive of the crime is what I have already suggested." "Very well; we shall clear it up at the post-mortem," was the doctor's reply, while at that moment Thomasson re-entered, followed by a police-officer in plain clothes and two constables in uniform. On their entry, Sainsbury introduced Sir Houston Bird, and told them his own name and that of his dead friend. Then the officer of the local branch of the Criminal Investigation Department sat down at the dead man's writing-table and began to write in his note-book the story of the strange affair, as dictated by Jack. Sir Houston also made a statement, this being followed by the man Thomasson, who detailed his master's movements prior to his death--as far as he knew them. His master, he declared, had seemed in excellent spirits all day. He had seen patients in the morning, had lunched frugally at home, and had gone down to Guy's in the car to see the wounded, as was his daily round. At six he had returned, dressed, and gone forth in a taxi to meet his friend, Mr Trustram of the Admiralty. They having dined together returned, and afterwards Mr Trustram had left and the doctor, smoking his pipe, had retired to his room to write. Nothing further was heard, Thomasson said, till the arrival of Mr Sainsbury, when the door of the room was found locked. "You heard no one enter the house--no sounds whatever?" asked the detective inspector, Rees by name, a tall, clean-shaven, fresh-complexioned man, with rather curly hair. "I didn't hear a sound," was the servant's reply. "The others were all out, and, as a matter of fact, I was in the waiting-room, just inside the door, looking at the newspapers on the table. So I should have heard anyone go up or down the stairs." Inspector Rees submitted Thomasson to a very searching cross-examination, but it was quite evident to all in the room that he knew nothing more than what he had already told. He and his wife had been in Dr Jerrold's service for eight years. His wife, until her death, a year ago, had acted as cook-housekeeper. "Did you ever know of Mr Lewin Rodwell visiting the doctor?" asked Sir Houston. "Never, as far as I know, sir. He, of course, might have come to consult him professionally when I've been out, and the maid has sometimes opened the door and admitted patients." "Have you ever heard Mr Rodwell's name?" "Only on the telephone to-night--and of course very often in the papers," replied the man. "Your master was very intimate with Mr Trustram?" inquired the detective.
