Greve shrugged his shoulders.
“I had been sitting in the billiard-room. It was rather stuffy, so I thought I’d like some air before tea!”
“You left Miss Trevert in the billiard-room?”
“Yes!”
“Why?”
Greve put a hand to his throat and eased his collar.
“The gong had sounded for tea,” the detective went on imperturbably; “surely it would have been more natural for you to have brought Miss Trevert with you?”
“I didn’t wish to!”
Mr. Manderton cleared his throat.
