The Gold Chromosome

When Adam Rottman's childless Aunt Sadie Gold died, the eight cousins learned her estate was in an irrevocable trust, the proceeds going to Adam's sister Sarah while she lives. After Sarah's death, the money would go to the last surviving cousin. It's a fatal tontine Adam's lawyer brother Harold set up. Would the cousins kill each other for one million dollars? Sarah's car is found in the river, but not Sarah. That begins a series of mysterious deaths. Coincidence? Or Murder? Who will be next? Adam and his psychologist wife Deborah must stop the chain before he, too, is eliminated.
