"You don't think that Dr. Binjoy was up in London on the night you met Caesar on the bicycle?"

"Noa, sir, I doan't. Whoy Muster Fellenger he were ill, he were; an' t' doctor he kep in t' sick room, he did. No one iver saaw him for daays, they didn't."

From this information, it seemed to Fanks as though there were an understanding between Sir Louis and the doctor. This old creature who represented the village opinion was quite sure that Dr. Binjoy had been in attendance on Fellenger on the night of the twenty-first. Yet Fanks knew by personal observation that Binjoy, under the name of Renshaw, had been in Tooley's Alley. He would not have returned to Taxton-on-Thames on that night, as the house in Great Auk Street had been watched. And yet Fanks had proved beyond all doubt that Renshaw and Binjoy were one and the same person. Was it possible that Sir Louis was telling a lie to screen Binjoy from the consequences of his being in town; and was it possible that the two had employed the negro, Caesar, to commit the crime, and then had smuggled him out of the way--say to Bombay--so that he should not betray them. In a word, were Fellenger and Binjoy guilty of the murder of the cousin of the former? It seemed impossible; and yet, as Sir Louis was employing Fanks to hunt down the assassin, it was hard to believe. The conversation of Simeon Wagg only introduced a new perplexity into this perplexing case.

There was nothing more to be got out of the old clerk; so Fanks retired to bed in a very melancholy frame of mind. He did not know which way to move in the midst of such contradictory information. The night brought counsel; and the next morning Fanks arose with a definite object. He would return to town and advertise for the negro. Caesar must have left his bicycle somewhere, so if he advertised for a negro in a green coat with brass buttons, he might find out something. Those with whom the bicycle had been left would be able to give a description of the negro who had arrived and departed with it; and so Fanks hoped to learn if the black murderer of Tooley's Alley was the same as the servant Caesar of Dr. Binjoy. Regarding the shielding of the doctor by Louis Fellenger, the detective resolved to leave that question until he went to Mere Hall and saw the two men together.

"I am afraid that Crate will have to go to Bombay, after all," said Fanks to himself as he left the hotel.

He did not go at once to town, as he wished to see both Hersham and Anne Colmer; also he was desirous of having an interview with the mother. Half-way down the street he met with the journalist, who saluted him in rather a sullen fashion.

"I was just about to call on you," said Hersham. "I wish to go to town by the midday train, if you have no objection."

"You can go as soon as you please," retorted Fanks, "you are not so much good to me that I care to keep you here."

"You need not make yourself so infernally disagreeable, Fanks," said the young man, tartly. "I have told you all I know, and so has Miss Colmer."

"As to that, I have my own opinion, Hersham. I certainly think that you and she have a secret between you which you will not share with me."
