“We must find out who it was!” went on the detective. “You make some inquiries. I'll take after her.”

“Could it have been Miss Viola?”

The question was answered almost as soon as it was asked, for, at that moment, Viola herself came down the front stairs.

“What is it?” she asked the two detectives. “Who cried out like that? Is some one hurt?”
