Rally 'Round the Corpse — Hy Conrad

It's been two years since her fiancé's death. Amy Abel needs to start over. What better way for a shy, risk-averse woman to start than to sink all her savings into a travel agency specializing in adventure? Her first project is a mystery road rally through the European countryside. At the starting line in Monte Carlo, Amy finds herself attracted to Marcus Alvarez, the most mysterious of her two dozen game-loving clients. But the rally gets off to a rocky start when an eccentric writer, the only person who knows the game's solution, is himself murdered back in New York. Who would kill a harmless mystery geek, and why are weird accidents beginning to happen along the way? To her horror, Amy discovers that this fictional mystery was based on a real, unsolved case, one that Marcus knows too much about. Now she has no choice but to join forces with Fanny, her domineering mother, and solve this on her own, before the killer strikes again.
