"Can you describe him to us?"

"Well, you see, sir, I hardly saw him. He had his back to me most of the time. He was a tall gentleman and dark; that's all I can say. He was dressed very like any other gentleman in a dark blue overcoat and a grey hat."

"Was he one of the passengers on the train?"

"I don't think so, sir; I took it that he had come to the station to see Mrs. Kettering in passing through. Of course he might have been one of the passengers; I never thought of that."

Mason seemed a little flurried by the suggestion.

"Ah!" M. Carrège passed lightly to another subject. "Your mistress later requested the conductor not to rouse her early in the morning. Was that a likely thing for her to do, do you think?"

"Oh yes, sir. The mistress never ate any breakfast and she didn't sleep well at nights, so that she liked sleeping on in the morning."

Again M. Carrège passed to another subject.

"Amongst the luggage there was a scarlet morocco case, was there not?" he asked. "Your mistress's jewel-case?"

"Yes, sir."
