Geiman, D: Last Dive

When the body of a friend, the deputy sheriff in the neighboring county, is found dead in his car, his widow calls Sheriff Redd Herring to help. But when Redd's investigation takes a dive into international territory, he quickly discovers that his routine procedures won't suffice. Did a liaison with a high-priced hooker go fatally wrong? Was the deputy sheriff dealing drugs? Or is something more ominous lurking? Redd had barely surfaced from a more local murder case-albeit one with a promising romance-before receiving the widow's call. Feeling slightly out of his league in both arenas, Redd turns to unorthodox means of investigation, knowing that his risks may cost him his job.
