I knew my way well enough, however, and set off homewards at a brisk pace; but as I turned into a narrow street I tripped and fell, just as a man rushed round the corner after me and fired a pistol at very short range, and then bolted like a rabbit.

My fall probably saved my life; and I jumped up and rushed after him, like a fool, instead of resting content with my narrow escape. But he disappeared round a corner and, as I darted after him, I ran into a couple of policemen who had heard the shot fired. As no one else was to be seen, they thought I had fired the shot and was running away; and despite all I could say, they insisted upon arresting me.

Fortune could not have served me a more scurvy trick at such a moment.

CHAPTER XXII

IN SEARCH OF THE BARON

Anyone who has ever lived in the capital of the German Empire, or indeed in any German town of size, knows the absolute futility of arguing with the police. Definite regulations are laid down for them, as the sand of the sea in number and an auctioneer's catalogue in precision of detail; and unless you are a person of infinite leisure and unruffled temper, you will do what they tell you and do it without remonstrance.

When they insisted upon detaining me upon suspicion of having fired the shot which had attracted their notice, I could not restrain a heated protest or two; but I soon ceased to remonstrate.

I chafed and fretted at the detention; and all the more so, because while one of them took charge of me, his companion made a long search for my assailant. He must have been an extremely conscientious fellow, for he showed more than German thoroughness in the search. They are very rarely quick in their methods, but they claim to be sure; and when he returned after nearly an hour, he had quite convinced himself that the man was not hidden anywhere near us.

"You must have fired the shot," he said, with an air of satisfied conviction, "or I should have found the man. There was no one else about." He then ran his hands down outside my coat, felt my revolver and drew it out. "Ah, I knew it," he exclaimed triumphantly.

"Do let us go to the station," I said impatiently.
