Every summer Dr. Bolton and his wife relived it. And every summer Judy went to stay with her grandmother Smeed, who scolded and fussed and tried to pretend she wasn’t glad to have her.

In another year she would be summering among the beautiful Thousand Islands and solving a mystery to be known as the Ghost Parade .

She and Lorraine had listened to this much of what Judy was telling them without interruption.
