What's the Sanibel Sunset Detective doing in London?

Tree Callister and his wife Freddie are in town to attend the wedding of Freddie's nephew. It promises to be a relaxing time, visiting family, seeing London's historic sites.

So then how does Tree end up following a mysterious young woman? Why are tattooed thugs banging him across the head and throwing him into the back of a van? In a city where no one has a gun, why is everyone pointing a gun at Tree?

From Portobello Road to the royal digs at Kensington Palace, from lively Piccadilly Circus to an ancient castle deep in the English countryside, Sanibel Island's most famous detective encounters brutal English gangsters, questionable Scotland Yard investigators, blackmail, and murder.
