"And Calvert came to the theatre at that time?"

"A few minutes before," said Hart, attacking some cheese.

"So he was disengaged on that evening up to that time. Ill at home?"

"He was away from the theatre, if that is what you mean," said the young man, "but he wasn't ill, so far as I know, in spite of what he said. It was a fake of some sort. I guess there was a girl in it."

"What do you mean?" asked Bocaros excitedly.

Hart started. "Why, nothing. Only some of our chaps were ragging him about getting away that evening to meet a girl."

"Did he deny that he was going to do so?"

"No. He laughed and coloured. A shy chap is Calvert."

Bocaros intervened. "Can you tell me what night this was?"

"What do you want to know for?" asked Hart suspiciously.
