Ben Sanders jumps out of a tenth-story window in New York, effectively ending his life, and leaving his wife, Carol, the beneficiary of his estate, provided she is not under psychiatric care at the time of his death.

Carol isn't.

But in the weeks following Ben's death (an accident? suicide?), she begins to wonder if she shouldn't be. And her doubts about her sanity multiply when she begins a trip to visit Ben's family in Florida. How else can she explain the disappearance of her cat, or hearing Ben's favorite song played over and over in the next motel room?

And there are other sinister happenings waiting for her.

With Richard Lockridge weaving his usual net of suspense, neither the reader nor Carol solves the problem until it's almost too late.
