He had a knife, but he never had a chance to use it. My champagne bottle descended on his head and he dropped like a log. There were men coming upstairs--not Chapman, for I still heard his hoarse shouts in the dining-room. If they once got up they could force me back through that hideous room by the door through which Docker had come, and in five minutes I should be in their motor-car. There was only one thing to do. I jumped from the stair-head right down among them. I think there were three, and my descent toppled them over. We rolled in a wild, whirling mass and cascaded into the dining-room, where my head bumped violently on the parquet. I expected a bit of a grapple, but none came. My wits were pretty woolly, but I managed to scramble to my feet. The heels of my enemies were disappearing up the staircase. Chapman was pawing my ribs to discover if there were any bones broken. There was not another soul in the room except two policemen who were pushing their way in from the street. Chapman was flushed and breathing heavily: his coat had a big split down the seams at the shoulder, but his face was happy as a child's. I caught his arm and spoke in his ear. "We've got to get out of this at once. How can we square these policemen? There must be no inquiry and nothing in the papers. Do you hear?" "That's all right," said Chapman. "These bobbies are friends of mine, two good lads from Wensleydale. On my road here I told them to give me a bit of law and follow me, for I thought they might be wanted. They didn't come too soon to spoil sport, for I've been knocking furriners about for ten minutes. You seem to have been putting up a tidy scrap yourself." "Let's get home first," I said, for I was beginning to think of the bigger thing. I wrote a chit for Macgillivray which I asked one of the constables to take to Scotland Yard. It was to beg that nothing should be done yet in the business of the restaurant, and above all that nothing should get into the papers. Then I asked the other to see us home. It was a queer request for two able-bodied men to make on a summer evening in the busiest part of London, but I was taking no chances. The Power-House had declared war on me, and I knew it would be war without quarter. I was in a fever to get out of that place. My momentary lust of battle had gone, and every stone of that building seemed to me a threat. Chapman would have liked to spend a happy hour rummaging through the house, but the gravity of my face persuaded him. The truth is I was bewildered. I could not understand the reason of this sudden attack. Lumley's spies must long ago have told him enough to connect me with the Bokhara business. My visits to the Embassy alone were sufficient proof. But now he must have found out something new, something which startled him, or else there had been wild doings in Turkestan.
