"So you had no intention of stealing the car when you set off to follow her to the beach?"
"Certainly not!" Tisdall said, as indignantly as if it made a difference. "It didn't even cross my mind till I came up the hill and saw the car waiting there. Even now I can't believe I really did it. I've been a fool, but I've never done anything like that before."
"Was she in the sea then?"
"I don't know. I didn't go to look. If I had seen her even in the distance I couldn't have done it. I just slung the buns in and beat it. When I came to I was halfway to Canterbury. I just turned her around without stopping, and came straight back."

"You still haven't told me how long you've been staying at the cottage?"
"Since Saturday midnight."
