If he expected an effect he did not get one. MacQueen said merely, “Oh! yes?” and waited for him to go on.

“You know the name perhaps?”

“Why, it does seem kind of familiar. Only I always thought it was a woman’s dressmaker.”

Hercule Poirot looked at him with distaste. “It is incredible!” he said.

“What’s incredible?”

“Nothing. Let us advance with the matter in hand. I want you to tell me, M. MacQueen, all that you know about the dead man. You were not related to him?”

“No. I am-was-his secretary.”

“For how long have you held that post?”

“Just over a year.”

“Please give me all the information you can.”

“Well, I met Mr. Ratchett just over a year ago when I was in Persia-”

Poirot interrupted.

“What were you doing there?’

“I had come over from New York to look into an oil concession. I don’t suppose you want to hear all about that. My friends and I had been let in rather badly over it. Mr. Ratchett was in the same hotel. He had just had a row with his secretary. He offered me the job and I took it. I was at a loose end and glad to find a well-paid job ready made, as it were.”

“And since then?”

“We’ve travelled about. Mr. Ratchett wanted to see the world. He was hampered by knowing no languages. I acted more as a courier than as a secretary. It was a pleasant life.”

“Now tell me as much as you can about your employer.”

The young man shrugged his shoulders. A perplexed expression passed over his face.

“That’s not so easy.”

“What was his full name?”

“Samuel Edward Ratchett.”

“He was an American citizen?”

“Yes.”

“What part of America did he come from?”

“I don’t know.”

“Well, tell me what you do know.”

“The actual truth is, Mr. Poirot, that I know nothing at all! Mr. Ratchett never spoke of himself or of his life in America.”
