For some moments as the train rattled along towards Exeter, Cheyne failed to grasp the significance of this last move. Then he saw that it was, as usual, part of a well-thought-out scheme. Approaching Teignmouth, Price had evidently left his compartment—almost certainly the fourth, where Lewisham sat—as if he were about to alight at the station. Instead of doing so, he had entered the lavatory. Disguised, or, more probably, with a previous disguise removed, he had left it before the train started from Dawlish, and appearing at the door of the second compartment, had attempted to convey the idea, almost certainly with success, that he had just joined the train. A further thought made Cheyne swing across again to the seat facing the engine. They were approaching Starcross. Would Lewisham adopt the same subterfuge at this station? But he did not, and they reached Exeter without further adventure. The train going no further, all passengers had to alight. Cheyne was in no hurry to move, and by the time he left the carriage Price and Lewisham were already far down the platform. He wished that he in his turn could find a false mustache and glasses, but he realized that if he kept his face hidden, his clothes were already a satisfactory disguise. He watched the two men begin to pace the platform, and soon felt satisfied that they were proceeding by a later train. They had reached Exeter at 5:02 P.M. Two expresses left the station shortly after, the 5:25 for Liverpool, Manchester and the north, and the 5:42 for London. Cheyne sat down on a deserted seat near the end of the platform and bent his head over his notebook while he watched the others. The 5:25 for the north arrived and left, and still the two men continued pacing up and down. “For London,” thought Cheyne, and slipping off to the booking hall he bought a first single for Paddington. If the men were traveling third, he would be better in a different class. When the London express rolled majestically in, Price and Lewisham entered a third near the front of the train. Satisfied that he was still unobserved, Cheyne got into the first class diner farther back. He had not been very close to the men, but he noticed that Lewisham had also made some alteration in his appearance, which explained his not having changed in the lavatory on the local train. The express was very fast, stopping only once—at Taunton. Here Cheyne, having satisfied himself that his quarry had not alighted, settled himself with an easy mind to await the arrival at Paddington. He dined luxuriously, and when at nine precisely they drew up in the terminus, he felt extremely fit and ready for any adventure that might offer itself.
