"Not later than 8," he said. "I must be out by 9. And, by the way, I may as well tell you now. After lunch tomorrow I am going to Brooklands. I return to Waterloo at 6:40. As I have to dine in the West End at 7:30, and my train may be a few minutes behind time, I want you to meet me with a suitcase at the hairdresser's place on the main platform. I'll dress there and go straight to my friend's house. It would be cutting things rather fine if I attempted to come here."
"I'll have everything ready, sir."
Bates was eminently reliable in such matters. He could be depended on to the last stud.
The storm which had raged overnight must have cleared the skies for the following day, because Theydon never enjoyed an outing more than his trip to the famous motor track. His business there, however, lay with aviation. A popular magazine had commissioned him to write an article summing up the progress and practical aims of the airmen and he was devoting afternoon and evening to the quest of information. A couple of experts and a photographer had given him plenty of raw material in the open, but he looked forward with special zest to an undisturbed chat that night with Mr. James Creighton Forbes, millionaire and philanthropist, whose peculiar yet forcible theories as to the peaceful conquest of the air were for the hour engaging the attention of the world's press.
He had never met Mr. Forbes. When on the point of writing for an appointment he had luckily remembered that the great man was a lifelong friend of the professor of physics at his (Theydon's) university, and a delightfully cordial introductory note was forthcoming in the course of a couple of posts. This brought the invitation to dinner. "On Tuesday evening I am dining en famille," wrote Mr. Forbes, "so, if you are free, join us at 7:30, and we can talk uninterruptedly afterward."
The train was not late. Bates, erect and soldierly, was standing at the rendezvous. With him were two men whom Theydon had never before seen. One, a bulky, stalwart, florid-faced man of forty, had something of the military aspect; the other supplied his direct antithesis, being small, wizened and sallow.
The big man had a round, bullet head, prominent bright blue eyes, and the cheek bones, chin and physical development of a heavyweight pugilist. His companion, whose dark and recessed eyes were noticeably bright, too, could not be more than half his weight, and Theydon would not have been surprised if told that this diminutive person was a dancing master. Naturally he classed both as acquaintances of his valet, encountered by chance on the platform at Waterloo.
He was slightly astonished, therefore, when the two faced him, together with Bates. A dramatic explanation of their presence was soon supplied.
"These gentlemen, sir, are Chief Inspector Winter and Detective Inspector Furneaux of Scotland Yard," said the ex-sergeant, in the awed tone which some people cannot help using when speaking of members of the Criminal Investigation Department.
Though daylight had not yet failed it was rather dark in that corner of the station, and Theydon saw now what he had not perceived earlier, that the usually sedate Bates was pale and harassed looking.
