From: Death Do Us Part, ed. Harlan Coben. Little, Brown, and Company, 2006.
Recently nominated for a Macavity Award, this darkly comic story focuses on a chemist and botanist married sixty years. Theirs is not an ideal union. Each is fully aware of the other's indiscretions, yet divorce is unthinkable. Instead, they celebrate each anniversary by preparing innocuous-looking, yet truly deadly dishes for a multi-course meal. Up to now, the husband and wife have each managed to deduce the forms of poison before taking that fatal bite.
