She passed out of the room shaking as with the ague. Fanks nodded in a satisfied way, and beckoning to Crate, he went upstairs. A frightened housemaid on the landing indicated the room of which they were in search; and they entered it to come face to face with the doctor summoned by the zealous landlady. He introduced himself as Dr. Renshaw, and made this announcement with a bland smile and a condescending bow. Fanks eyed his tall and burly figure; his Napoleonic countenance; his smooth, brown beard and his perfect dress. There was a look about the man which he did not like; and he mistrusted the uneasy glance of the hard, grey eyes. The detective relied largely on his instinct. In this case it warned him against the false geniality of Dr. Renshaw. "The representatives of the law, I believe," said the medical man in a deep and rolling voice. "I was about to take my departure; but if I can be of service in the interests of justice, pray command me." "I suppose there is no doubt that our friend there is dead," said Fanks. "Dead as Caesar, sir," said the magnificent doctor, waving his arm. "Caesar died by steel," remarked Fanks significantly. "It appears that this man died in an easier manner." "There is another parallel," said the doctor, condescending to add to the historical knowledge of the detective. "If we may believe Brutus, the great Julius was slain as a traitor to the republic. This unknown man," added Renshaw, pointing to the body, "also died the death of a traitor." "If, as you say, the dead man is unknown," said Fanks quickly, "how can you tell that he was a traitor?" "By inference and deduction," was the reply. "You can judge for yourself. Far be it from me that I should set my opinion against that of the law; but I have a theory. Would you care to hear it? If I may venture on a jest," said Renshaw with ponderous playfulness, "the medical mouse may help the legal lion." "Let us hear your theory by all means," said Fanks easily, "but first permit me to speak with my assistant." The doctor bowed and passed over to the other side of the bed; while Fanks went with Crate to the door. Here he hesitated, glanced at the doctor, and finally led his subordinate into the passage. "Crate!" he said in a rapid whisper, "I mistrust that man. He will shortly leave this place. Follow him and find out where he lives. Then set someone to watch the place, and return to me." "Do you think that he has anything to do with it?" asked Crate. "I can't say at present. I may be wrong about him and about Mrs. Boazoph; all the same I mistrust the pair of them. Now off with you."
