M. Hercule Poirot, having nothing better to do, amused himself by studying her without appearing to do so.

She was, he judged, the kind of young woman who could take care of herself with perfect ease wherever she went. She had poise and efficiency. He rather liked the severe regularity of her features and the delicate pallor of her skin. He liked the burnished black head with its neat waves of hair, and her eyes-cool, impersonal and grey. But she was, he decided, just a little too efficient to be what he called “jolie femme.”

Presently another person entered the restaurant car. This was a tall man of between forty and fifty, lean of figure, brown of skin, with hair slightly grizzled round the temples.

“The Colonel from India,” said Poirot to himself.

The newcomer gave a little bow to the girl. “Morning, Miss Debenham.”

“Good morning, Colonel Arbuthnot.”

The Colonel was standing with a hand on the chair opposite her.

“Any objections?” he asked.

“Of course not. Sit down.”

“Well, you know, breakfast isn’t always a chatty meal.”

“I should hope not. But I don’t bite.”

The Colonel sat down. “Boy,” he called in peremptory fashion.

He gave an order for eggs and coffee.

His eyes rested for a moment on Hercule Poirot, but they passed on indifferently. Poirot, reading the English mind correctly, knew that he had said to himself. “Only some damned foreigner.”

True to their nationality, the two English people were not chatty. They exchanged a few brief remarks and presently the girl rose and went back to her compartment.

At lunch time the other two again shared a table and again they both completely ignored the third passenger. Their conversation was more animated than at breakfast. Colonel Arbuthnot talked of thePunjab and occasionally asked the girl a few questions aboutBaghdad where, it became clear, she had been in a post as governess. In the course of conversation they discovered some mutual friends, which had the immediate effect of making them more friendly and less stiff. They discussed old Tommy Somebody and old Reggie Someone Else. The Colonel inquired whether she was going straight through to England or whether she was stopping in Stamboul.
