"Though I have found out a good deal," he said, "I am still utterly at a loss to know what these fellows have been up to. Of course, I quite understand that there is some underhand business with regard to certain coins--but then those coins are real gold, and it would not pay anybody to counterfeit sovereigns worth twenty shillings apiece." "You don't think so," Egan said, drily. "We shall be able to prove the contrary presently. But hadn't you better wait, sir, till the critical moment comes?" "Very well," Venner laughed good-naturedly. "I'll wait and see what dramatic surprise you have in store for me." The powerful car sped over the roads heedless of police traps or other troubles of that kind, and some time before the appointed hour for the arrival of Blossett's train in London they had reached Victoria. It was an easy matter to store the car in a neighboring hotel, and presently they had the satisfaction of seeing Blossett swagger from a first-class carriage with a heavy Gladstone bag in his hand. He called a cab and was rapidly driven off in the direction of the city. Egan in his turn called another cab, giving the driver strict injunctions to keep the first vehicle in sight. It was a long chase, but it came to an end presently outside an office in Walbrook. Blossett paid his man and walked slowly up a flight of steps, carrying his bag. He paused at length before a door which was marked "Private," and also placarded the information that here was the business place of one Drummond, commission agent. Scarcely had the door closed on Blossett than Egan followed without ceremony. He motioned the other two to remain behind; he had some glib story to tell the solitary clerk in the outer office, from whom he gleaned the information that Mr. Drummond was engaged on some particular business and could not see him for some time. "Very well," he said; "I'll wait and read the paper." He sat there patiently for some five minutes, his quick ears strained to catch the faintest sound of what was taking place in the inner office. There came presently the chink of metal, whereupon the watcher whistled gently and his comrade and Venner entered the room. Very coolly Egan crossed over and locked the door. "Now, my young friend," he said to the astonished clerk, "you will oblige me by not making a single sound. I don't suppose for a moment you have had anything to do with this; in fact, from your bewildered expression, I am certain that you haven't. Now tell me how long have you been in your present situation." "About three months," the clerk replied. "If you gentlemen happen to be police officers--" "That is exactly what we are," Grady smiled. "Do you find business brisk--plenty of clients about?"
