“No, after, dear,” said Derry gallantly.

“Oh, I used her after midnight.” She turned to her husband. “I felt I must have some air, so I sent for Filmer and went for a little drive.”

“I can’t say I do,” said Virginia ruthlessly. “Never mind.” She turned to the constable. “This gentleman says he was with me.”
