"The Millionaires' Train," as it is sometimes called, swung round a curve of line at what seemed a dangerous speed. Van Aldin, Knighton, and Poirot sat together in silence. Knighton and Van Aldin had two compartments connecting with each other, as Ruth Kettering and her maid had had on the fateful journey. Poirot's own compartment was farther along the coach.
The journey was a painful one for Van Aldin, recalling as it did the most agonising memories. Poirot and Knighton conversed occasionally in low tones without disturbing him.
