some moments.

"Yes," she replied reflectively. "She has enemies, I know. But who has
not?"

"Is there any person who, to your knowledge, would have any motive to
kill her?"

Again she was silent.

"There are several people who hate her. One of them might have done it
out of revenge. You say you saw nobody?"

"Nobody."

"Why did you go and see her at that hour?" asked the girl.

"Because I wanted her to tell me something--something of greatest
importance to me."

"And she refused, of course? She keeps her own secrets."

"No. On the other hand, she was about to disclose to me the information
I sought when someone fired through the open window."

"And what was your father's name?" asked Lisette in a strangely altered
voice.

"Henfrey."

"Henfrey!" gasped the girl, starting up at mention of the name.
"_Henfrey_! And--and are--you--_his son_?"

"Yes," replied Hugh. "Why? You know about the affair, mademoiselle! Tell
me all you know," he cried. "I--the son of the dead man--have a right to
demand the truth."

"Henfrey!" repeated the girl hoarsely in a state of intense agitation.
"Monsieur Henfrey! And--and to think that I am here--with you--_his
son_! Ah! forgive me!" she gasped. "I--I----Let us return."

"But you shall tell me the truth!" cried Hugh exci
