“Have you any idea what took place between them? Was there any quarrel?”

“I should not call it a quarrel, sir. I never heard the stranger's voice raised once, though I could not help but hear Mr Vereker shouting occasionally. It is my belief that it was money the man wanted, for Mr Vereker said, “Not one penny do you get out of me!” several times.”

“Did you hear him say anything else?”

“Not a great deal, sir. The term scoundrel was frequently made use of, and Mr Vereker said once, very loudly: “So you think you can frighten me, do you?” But what the other man replied I don't know, him speaking all the time in a soft voice. After a little while Mr Vereker seemed to calm down, and I was unable to catch what was said. But at ten minutes to eight they both came out of the library, and by the way Mr Vereker damned me for being in the hall to open the door for him I judged that something had happened to put him in a bad temper. The other man was as amiable as ever, and seemed to be laughing up his sleeve, to my way of thinking. He said Mr Vereker could give him a lift, and Mr Vereker threw him a look which quite startled me, accustomed as I was to his moods. I could see he hated the man, and it is my belief that he had a deal of trouble forcing himself to agree to take him in the car with him. But whatever the reason he did actually do so, the stranger making himself very much at home, and Mr Vereker with his mouth shut like a trap. That, sir, is the last I ever saw of Mr Vereker.”

The Superintendent had listened to this story with an unmoved countenance. “Would you know the man if you were to see him again?”

“I think so, sir. I should, I believe, recognise both his smile, and his voice. His person was not, however, in any way remarkable.”

“Very well. You do not know of anyone else who may have visited Mr Vereker on Saturday?”

“Mr Vereker was at his office until lunch-time, sir, and no one called at this house during the afternoon. He went out at four o'clock, and did not return until shortly before seven. Miss Vereker rang up at about six, but my orders being to inform anyone who wanted him that he had gone out of town, I did so.”

“Do you know why Mr Vereker gave that order?”

“It was not unusual, sir. He had been out of temper all day, and when that occurred he never wanted to see or speak to anyone, least of all a - a member of his family.”
