The night was dark, and French could not take minute stock of his surroundings, but he presently learnt from the sounds of his car’s wheels that Oaklands was reached from the road by an appreciable drive coated with fine gravel, and the bulk of the house, looming large above him as he stood before the porch, indicated an owner well endowed with this world’s goods. The impression was confirmed when in answer to his inquiry a venerable butler conducted him through a hall of imposing dimensions to a luxurious sitting-room. There the man left him, returning in a few minutes to say his master was in the library and would see Mr. French. Colonel FitzGeorge was a tall, white-haired man, with an erect carriage and excessively courteous manners. He bowed as French entered, and indicated a deep leather-lined arm-chair drawn up opposite his own before the blazing fire of pine logs. “A chilly evening, Inspector,” he said pleasantly. “Won’t you sit down?” French thanked him, and after apologising for the hour of his call, went on: “My visit, sir, is in connection with certain bank-notes which I am trying to trace. Some time ago there was a robbery in the City in which a number of Bank of England notes were stolen. The owner fortunately was able to find out their numbers from his bank. When the matter was reported to us, we naturally asked the banks generally to keep a lookout for them. Nothing was heard of them until to-day, but this afternoon, just before closing time, two of them were paid into the Reading Branch of the City of London Bank. The teller, though not certain, believed that you had paid them in. You can see, therefore, the object of my call. It is to ask you if you can possibly help me to trace the thief by telling me where you received the notes. There were two, both for ten pounds, and the numbers were A/V 173258 W and N/L 386427 P.” Colonel FitzGeorge looked interested. “I certainly called at the bank this afternoon and lodged some money,” he answered. “It was mostly in the form of dividend warrants, but there were a few notes. Now where did I get those? I should be able to tell you off-hand, but I’m not at all sure that I can. Let me think, please.” For some moments silence reigned in the luxuriously-furnished room. French, always suspicious, surreptitiously watched his new acquaintance, but he had to admit that he could discern none of the customary signs of guilt. But he reminded himself that you never knew, and determined that unless he was completely satisfied by the coming reply, he would make an investigation into Colonel FitzGeorge’s movements on the night of the murder. “I _believe_,” said the Colonel suddenly, “I know where I got those notes. I am not by any means certain, but I think I can tell you. Unless I am very much mistaken, it was from the manager of the Hotel Beau-Sejour in Chamonix.” “Chamonix?” French repeated in surprise. This was by no means what he had expected to hear.
