Dimsdale was annoyed that his pet project of a marriage could not come to pass, but there was no help for it, as he could not govern the young man's affections. Also he was annoyed because Vernon, when the death of his father occurred, would not let the elder man assist him. However, he told him his plans about the private inquiry office, and although the ex-police commissioner did not wholly approve, he judged from his knowledge of the young man's detective powers, that it was the best use he could put his talents to. More than this, he managed to bring him clients, and to spread the fame of Nemo by dexterous allusions. Vernon therefore was doing very well in the line he had struck out for himself, and felt duly grateful to Dimsdale for his assistance. He thought as he walked along Ralph Street that probably the old gentleman had found him a fresh client. But it was odd that Colonel Towton's chambers should have been chosen as the meeting place, since Dimsdale belonged to several clubs. And the matter, whatever it was, must be very important, else Dimsdale would have waited until Vernon paid his weekly visit to the Hampstead bungalow. It was only a quarter-past ten o'clock when Vernon arrived, and he thought that he would have to wait. But Towton's servant intimated that Mr. Dimsdale was watching for his visitor in the Colonel's particular sanctum, and ushered the young man into the room, after relieving him of his coat and hat. The Colonel himself did not appear to be present, but Martin Dimsdale was smoking in a deep arm-chair, and jumped up in his boyish way to shake hands warmly. He always had a great regard for Arthur Vernon. The room was an ordinary apartment, comfortably furnished, but in a strictly bachelor fashion. The scheme of colour was deep green and deep red, so that it appeared somewhat sombre. Trophies of Towton's sporting instincts in the shape of skins and heads appeared on the walls and on the floor. There were many military portraits and groups about, reminiscent of the Colonel's army life. The two windows were open and the curtains were pulled back, so that the room was fairly cool, while on the table stood a syphon, some glasses and a decanter of whisky, together with a box of cigars. These were at Mr. Dimsdale's elbow. He had evidently been passing the time in smoking and drinking pending his young friend's arrival. "I'm glad to see you, boy," said the ex-police commissioner, pointing to a chair. "Sit down and make yourself at home. Towton gives me full permission to play in this yard. Have a peg and a cigar." "Not too strong, please," warned Vernon, accepting a cigar and sinking into the indicated chair. "I haven't so steady a head as yours." "It's a cleverer head," said Dimsdale, squirting in the potash. "Else I should not have asked you to meet me here--Nemo." "Oh!" Vernon placed the glass beside him. "I thought it was a Case. But why did you ask me to meet you in Towton's rooms, and where is Towton?"
