It all began for Natalie Garrett as an idyllic vacation at her grandfather's estate near the resort of Beach Haven. Summer was over, the tourists had left, the forest and lake were hers to enjoy undisturbed. -- But Natalie had not counted on a handsome stranger named Bill Brown, his life haunted by a terrible crime. Or on the mysterious Swedish count and countess, with their strange links to a nightmare Nazi past. Or on the horror that opened up before her terror-bright eyes as she stumbled upon a secret it was death to discover, and trembled in the arms of a lover she could neither trust or resist...
Bill Brown walked out of the courtroom-free, but under the shadow of suspicion. As a supposed Red, he could be sent into a Midwest territory where actual Communists were suspected of conducting a vicious experiment. It might be any of a dozen Beach Haven residents who were preparing to stay on after the carnival season was over. (From the book)
