"There's one thing I should like to add, Mr. Dryden," he said, just before we parted. "If you ever find yourself in real difficulty or actual danger, don't hesitate to let me know. Whatever I'm doing I shan't be too busy to lend you a hand."

I tried to thank him, but, without waiting to listen, he stepped off into the roadway, and a moment later he was swallowed up amongst the traffic.

Brief as our interview had been, however, it had left me in a very satisfied frame of mind. From what I had seen of the Inspector I felt pretty sure that if there was anything worth knowing about Manning's past career he would soon succeed in ferreting it out. Apart from that, the knowledge that in a tight corner I should have him as well as Bobby at my back was the kind of encouraging thought that would have put heart into a rabbit.

My good spirits were in no way damped by one or two drops of rain, which at that moment, much to my surprise, began to dot the pavement. Looking up, I noticed for the first time that a change was taking place in the weather. A great bank of cloud was creeping slowly up from the east, and spreading in a black, threatening line all across the sky.

Manning's prophecy at once came into my mind, but, not being particularly anxious for a ducking, I wasted no time in further reflections. Hailing a passing taxi, I instructed the man to take me back to the Great Eastern Hotel, which I reached in comfort and dryness just as the rain began to descend in a steady drizzle.

There was nothing to do under the circumstances but to make the best of things indoors. I am never at a loss how to amuse myself if I can get a game of billiards, and I soon discovered that the hotel possessed a couple of excellent tables, presided over by a red-headed marker, who spoke Scotch and looked as if he drank it.

We played several hundred up with varying success; and at six-thirty, feeling quite ready to face a good dinner, I set out for Mr. Drayton's club. As an additional encouragement to my appetite I walked the whole way to St. James's Street, for by this time, although the pavements were still wet, the rain itself had practically ceased falling.

The club proved to be a big, sombre establishment, inhabited chiefly by middle-aged gentlemen of a distinctly morose aspect. What they had to be morose about I can't imagine, for a better meal than the one put before us I never wish to eat. Mr. Drayton, who was waiting for me in the hall and conducted me straight into the dining-room, confessed frankly that he had joined the place purely for the sake of its excellent cooking, and the respect which I already had for his judgment rose steadily with each succeeding course.

After dinner we made our way to the smoking-room upstairs, where, with the assistance of a couple of leather arm-chairs and a plentiful supply of whisky and soda, the time passed away so pleasantly that it was close on midnight before I got back to my own bed at the hotel.

The whisky must have been of the same high quality as the rest of the food, for in spite of the amount that I had put away, I woke up next morning feeling remarkably fit and cheerful. One of the first things I did was to pull aside the blind and have a look at the weather. The result was not encouraging, for my window faced on to a blank wall of dirty white brick, and in the intervening space a thin grey drizzle was coming down with monotonous persistence.
