How does one detective end up married four times? A good question, Tree Callister wishes he had the answer. All he knows is that three of his ex-wives have arrived on Sanibel Island, off the west coast of Florida, much to the chagrin of Freddie, his fourth wife. What's more, all his ex-wives are in trouble. Before Tree knows it, he is up to his neck in complications, including a jailed ex-wife, his best friend under arrest, a Russian oligarch who doesn't like him, cops out to get him... A murder or two. And, oh yes, Marilyn Monroe shows up unexpectedly. At a time when he is supposed to be retired and enjoying a quiet life on an island paradise, Tree finds himself in bigger jams than ever, trying to stay alive while he searches for a killer and asks himself that age old question: how does a private detective get married so many times? Ron Base's latest Tree Callister adventure, The Four Wives of the Sanibel Sunset Detective, tries to find the answer. Sort of.
