“Did you use your car at all on Saturday?”

“No, I don't think I - Oh yes, I did, though!”

“At what time?”

“Well, I don't really remember. In the afternoon.”

“And when did you return it to the garage?”

Mesurier uncrossed his legs, and then crossed them again. “It must have been sometime during the early part of the evening. I'm afraid I'm a bit hazy about times. And of course, not knowing that it would be important - the time I garaged the car, I mean -”

“Are you sure, Mr Mesurier, that when you say the early part of the evening, you don't mean the early part of the morning?”

“I - I don't understand you. I've already told you I went to bed early. I don't quite follow what you're driving at. I mean, if you think I had anything to do with Arnold Vereker's death it's too utterly absurd.”

“The proprietor of the hour lock-up garages in the mews,” said Hannasyde, consulting his notes, “states that you took your car out at approximately five o'clock.”

“I daresay he's quite right. I certainly shan't dispute it. I told you it was during the afternoon. What I don't understand is why you should be so interested in my movements. Frightfully thorough of you, and all that, but I must say I find it rather amusing that you should actually take the trouble to question them at the garage!”
