"When did this happen?" asked Ashton-Kirk, of Drevenoff.

"The murder?"

"Of course!" sharply.

"I don't know the hour. Some time to-night."

"How was it done?"

"He was shot through the chest."

"Where?"

"In his library."

It is natural, under such circumstances, for an informant to become very voluble; but not so Drevenoff. His answers were brief; his manner, too, was sullen and unwilling.

"Tell me what you know about it," requested Ashton-Kirk.
