“Then it must be your friend’s: the man who was here must have dropped it.”

“He would not have had a rag like this.”

“Then it’s Lotta’s; she is the woman at the lodge; feckless enough for any rag.”

When he entered, he stood still for a few seconds listening intently: then he looked under the table, behind the chair, behind the curtains and into the outer passage. Finding nothing suspicious, he returned, locked the window door and drew the curtains across it.

His sister entered the room behind him.
