Captains Outrageous

The cover of this book is completely inaccurate, that scene never happened. Someone died in a pool, but it was a man.
At any rate :) Hap is in a bit of a rut. His relationship with Brett has cooled since he and Leonard helped rescue Tillie. He's working at a chicken processing plant as a security guard, and one night while leaving work he stops a man who is attacking a young teenage girl. Turns out the girl's father is the wealthy owner of the chicken plant, and he gives Hap $100,000 (Hap protests that he didn't do it for the money, and Charlie talks him into accepting it so as not to hurt the father's pride) and gives Hap and Leonard a one month paid vacation from the plant. Leonard's new boyfriend, John, convinces them they should take a cruise. They cheap out though, and end up on a real tub. Their vacation gets even worse when they miss the shuttle back to their boat after an excursion to a Mexican village, and are stranded there. Leonard is stabbed during a mugging attempt, and an old man named Ferdinand rescues them and takes them on his fishing boat.
That was only about halfway through the book, if you can believe it. It was dense. Very, very good though. The worst part was that Charlie was murdered, after being mistaken for Hap. That made me cry, I liked Charlie.
