 Our return progress towards London was an interrupted one. We deviated from the main road more than once, and occasionally stopped at a small building, which I had no difficulty in recognizing as a cottage hospital. Poirot only spent a few minutes at each, but at every halt his radiant assurance was more and more restored.

He whispered something to Norman, to which the latter replied:

"Yes, if you turn off to the left, you will find them waiting by the bridge."

We turned up a side road, and in the failing light I discerned a second car, waiting by the side of the road. It contained two men in plain clothes. Poirot got down and spoke to them, and then we started off in a northerly direction, the other car following close behind.

We drove for some time, our objective being obviously one of the northern suburbs of London. Finally, we drove up to the front door of a tall house, standing a little back from the road in its own grounds.

Norman and I were left with the car. Poirot and one of the detectives went up to the door and rang. A neat parlourmaid opened it. The detective spoke.
