“Very sorry, sir; of course, any information you may see fit to give the police will be acted on accordingly; but you see it’s against our regulations to take civilians about with us when we’re on duty, that’s how it is. Not but what, as it’s all between friends, I don’t mind taking you gentlemen downstairs and showing you the other door of that there passage as you didn’t see and I came in by.” The fact that Carmichael was still at his useless post occurred to the two friends at this point, and made them consent to the indignity of a personally conducted tour. “In a cellar the other door is, but it’s a cellar you have to get to from the outside,” the sergeant explained, leading the way downstairs. They were not destined to complete, on that occasion, their experiences of the passage. They had only just got out of the front door when the whirlwind figure of a second policeman almost cannoned into them, and their attention was directed to a motor-cycle, with side-car, just disappearing through the lodge gates. “It’s ’im,” panted the new-comer. “Gone off on the blinking bus!” The mystery man had disappeared, and disappeared, with singular effrontery, on the very vehicle on which the representatives of the law had come to track him down. “Come on, Sergeant,” shouted Reeves, rising to the occasion. “I’ve got my car only just round here, and she’ll do a better pace than anything else you could pick up!” And, while the agitated sergeant explained to Gordon the message he wanted telephoned to the station at Binver, Reeves did a record time in starting and bringing round to the front his new Tarquin “Superbus.” It was scarcely three minutes since the disappearance of the adventurous stranger when the two policemen, one at Reeves’ side and one luxuriously cushioned in the tonneau, bounded off down the drive in pursuit. “What does that car of yours do, Sergeant? Forty? I can knock fifty out of this easily, as long as we don’t get held up anywhere. I say, what happens if some of your friends want to run me in for furious driving?”
