The Two Sanibel Sunset Detectives — Ron Base

Joshua and Madison are pretty smart kids. Except they have no idea what their father does for a living. They suspect the worst. That's where Private Detective Tree Callister comes in. Josh and Madi want him to find out what their father does, and why he keeps disappearing. But Tree has problems of his own. Everyone on Sanibel Island thinks he's hiding nine million dollars that has gone missing. The FBI is investigating him, the local cops are out to get him-and they are not happy that Tree keeps stumbling across dead bodies. Then there is the diminutive, dangerous Paola who has no hesitation about killing anyone who gets in her way. Including Tree. It's looking as bad as it ever has for Tree Callister in his latest-and most deadly-adventure. And it's only going to get worse.
