"That's the man," agreed Foyle, not without a note of rueful admiration. "He'd got half-a-dozen of the best-known and richest peers in England to promise support, when we spoilt his game. No one would prosecute. He always had luck, had Goldenburg. He's been at the back of a score of big things, but we could never get legal proof against him. He was a cunning rascal--educated, plausible, reckless. Well, he's gone now, and he's given us as tough a nut to crack as ever he did while he was alive." "How did you get his finger-prints if he was never convicted?" asked Sir Hilary with interest. Foyle looked his superior full in the face and smiled. "I arrested him myself, on a charge of pocket-picking in Piccadilly," he said. "Of course, he never picked a pocket in his life--he was too big a crook for that. But we got a remand, and that gave us a chance to get his photograph and prints for the records. We offered no evidence on the second hearing. It was perhaps not strictly legal, but----" The superintendent's features relaxed into a smile. "He never brought an action for malicious prosecution." "And about Grell? How do you propose to find him?" Foyle drew his chair up to the table and scribbled busily for a few minutes on a sheet of paper. He carefully blotted it, and handed the result of his labours to Sir Hilary, who nodded approval as he read it. "You think we shall catch one man by advertising for another?" "I think it worth trying, sir," retorted the superintendent curtly. "The description and the photograph fit like a glove--and we shan't be giving anything away." As Heldon Foyle passed through the little back door leading to the courtyard of Scotland Yard an hour later, he stopped for an instant to study a poster that was being placed among the notices on the board in the door. It ran: POLICE NOTICE. £100 REWARD HARRY GOLDENBURG, alias THE HON. RUPERT BAXTER, MAX SMITH, JOHN BROOKS, etc. Wanted For MURDER. DESCRIPTION.--Age, about 45; height, about 6 ft. 1 in.; complexion, bronzed; square features; grey hair; drooping grey moustache; upright carriage. NOTE.--Henry Goldenburg has travelled extensively, and is an American by birth, but his accent is almost imperceptible. He speaks several languages, and has resided in Paris, Madrid, and Rome. The above Reward will be paid to any person (other than a member of any Police force in the United Kingdom) who gives such information as will lead to the apprehension of the above-named person. The superintendent had wasted no time. CHAPTER VII The first grey daylight had found Sir Ralph Fairfield pacing his sitting-room with uneven strides, his hands clasped behind his back, the stump of a cold cigar between his teeth. His interview with Heldon Foyle had not been calculated to calm him. "I'm a fool--a fool," he told himself. "Why should they suspect me? What have I to gain by Grell's death?"
