"When you combine the ideas of whistles at night, the presence of

a band of gipsies who are on intimate terms with this old doctor,

the fact that we have every reason to believe that the doctor has

an interest in preventing his stepdaughter's marriage, the dying

mystery may be cleared along those lines."

"I cannot imagine."

"I see many objections to any such theory."

"And so do I. It is precisely for that reason that we are going

to Stoke Moran this day. I want to see whether the objections are

fatal, or if they may be explained away. But what in the name of

the devil!"
