“-and so my daughter said, ‘Why,’ she said, ‘you just can’t apply American methods in this country. It’s natural to the folks here to be indolent,’ she said. ‘They just haven’t got any hustle in them-’ But all the same you’d be surprised to know what our college there is doing.

The train plunged into a tunnel. The calm, monotonous voice was drowned.

At the next table, a small one, sat Colonel Arbuthnot-alone. His gaze was fixed upon the back of Mary Debenham’s head. They were not sitting together. Yet it could easily have been managed. Why?

Perhaps, Poirot thought, Mary Debenham had demurred. A governess learns to be careful. Appearances are important. A girl with her living to get has to be discreet.

His glance shifted to the other side of the carriage. At the far end, against the wall, was a middle-aged woman dressed in black with a broad, expressionless face. German or Scandinavian, he thought. Probably the German lady’s-maid.

Beyond her were a couple leaning forward and talking animatedly together. The man wore English clothes of loose tweed, but he was not English. Though only the back of his head was visible to Poirot, the shape of it and the set of the shoulders betrayed him. A big man, well made. He turned his head suddenly and Poirot saw his profile. A very handsome man of thirty-odd with a big fair moustache.

The woman opposite him was a mere girl-twenty at a guess.
