“Did you go to Miss Williams' house?”

“Flat. Yes, but she was out. No one answered the bell, so I drifted along to some cinema or other. No, I don't know which one it was and I don't know what the film was called, because I went in after it had started, and it was so dull I slept through most of it.”

“Well, what did you do when you left the cinema?”

“Went for a walk,” replied Kenneth.

“Where to?”

“Richmond.”

“Why on earth did you do that?” said Giles, patient but despairing.

“Why not?” retorted Kenneth. “It was a fine night, and very warm, and I'd had a nice nap in the cinema. It seemed an obvious thing to do.”

“Did it!” said Giles.

“But he does go for walks at night, Giles!” Antonia put in anxiously. “We both do, when it's too hot to go to bed.”
