“I seem to remember the name,” he said slowly. “Double Dan? Isn’t that the man who impersonates people?” “You’ve got it, sir,” said Mr. Superbus. “He don’t impersonate them, he _is_ them! Take Mr. Mendlesohn----” Now Gordon remembered. “You’d never think anybody could impersonate him, though, with his white whiskers and him not being married, it wasn’t so hard. He got away with eight thousand pounds, did Dan. Got Mr. Mendlesohn out of the way, walked into his private office and sent a new clerk out with a cheque. That’s why Mr. Mendlesohn’s gone into the country. He daren’t hold up his head.” “Oh, I see,” said Gordon slowly. “You’re acting on behalf of----?” “The Brokers’ Association--he goes after brokers.” Gordon seldom laughed, but he was laughing softly now. “And you have been following me round to protect me, eh?” “Not exactly that, sir,” said Mr. Superbus with professional reserve. “What I was trying to do was to get to know you, so that I’d make no mistake if Dan tried to ‘double’ you.” “Have a cigar?” said Gordon. Mr. Superbus said he didn’t mind if he did; that he would take it home, and smoke it in the seclusion of his own house. “My good lady likes the smell of a cigar,” he said. “It keeps away the moths. I’ve been married now for three and twenty years, and there isn’t a better woman on the face of the earth than my good lady.” “A Roman?” asked Gordon. “No, sir,” replied Mr. Superbus gravely. “Devonshire.” Diana, coming into the room half an hour later, saw Gordon standing with his back to the fireplace, his hands clasped behind him, his head slightly bent, a picture of practical thought. “Who was that funny little man I saw go out of the house?” she asked. “He is a man named Superbus,” said Gordon, roused from his reverie with a start, “who has been making certain enquiries. He’s been trying to trace somebody who has robbed a man of eight thousand pounds.” “Oh!” said Diana, and sat down quickly. The ghost of the late Mr. Dempsi was very active at that moment. CHAPTER VII Diana liked Bobbie Selsbury the moment she saw him. He was a smaller edition of his brother, a brusque, cynical young man, with a passion for revue and the more clingy variations of modern dancing. Also he was engaged to a girl in Canada, and had no intense interest in any other woman. She liked him most because he was entirely without that brand of soul which wriggled so frequently under the scalpel of his brother. He came to dinner twice, and on the second occasion Gordon thought his relative was on sufficiently good terms with his unwanted guest, to discuss openly the impropriety of her continued stay.
