Summary
When a young fireman died from what appeared to be serious but undiagnosed heart disease, his family and friends were devastated but they had no proof of foul play.

Then they learned that, six years earlier in a nearby town, a young police officer died in the same way. The men had one thing in common: At the time of their deaths, they were married to the same woman, Lynn Turner.
