So we went to take a look. It took an hour and forty minutes to get there, first south and then west. A lonely road on the edge of the Glades. Lumpy asphalt running string-straight through wetlands past wooded hammocks where the white birds sat on bare trees like Christmas doodads, thinking white bird thoughts.
As I think I may possibly have mentioned before, I’m a hopeless fan of John D. MacDonald, and especially his Travis McGee novels, about a Florida boat bum and “salvage specialist” who recovers people’s stolen property and keeps half the value as his fee.  The Lonely Silver Rain holds a special place in the series, as its 21st and final installment. It was published in 1985, and the author died the following year.
Trav gets a call from Billy Ingraham, an old friend who’s a millionaire and a widower, who recently retired, acquired a trophy wife, and had a yacht custom-built to his specifications. The boat had barely gotten in the water when somebody stole it. Billy has heard that Trav once found somebody else’s stolen yacht. Could he do the same for him? Trav explains that the first recovery was kind of a fluke, but Billy promises a generous finder’s fee. Helped by his best friend, the economist Myer, Trav makes a plan to use aerial photography and systematic analysis to try to find the needle in the haystack. And, to his own surprise, he does find it.
But when he boards the yacht, now abandoned in an isolated bay in the Keys, he finds it trashed, with three corpses inside. A young man and two young women have been tortured and murdered here. Trav recognizes the signs – this is a drug deal gone bad. This is nothing for outsiders to mess with.
Trav backs out carefully, covering his tracks, and phones the Coast Guard anonymously to alert them. Then he tells Billy to forget he was ever involved.
Too late, it turns out. One of the dead women was the daughter of a high-level Peruvian gangster. Someone has decided that somebody must be made to pay for the murders, and somehow they’ve identified Travis McGee as the scapegoat. He’ll have to either handle the problem or find a way to disappear forever.
I remember that, when this book came out, some reviewers commented on what they saw as a weary, graying quality. The author’s chronological plan was for Travis McGee to age at a somewhat slower rate than people in the real world. Under that plan, McGee was now middle-aged, but still had good years in him (though he worries now and then about losing a half-step). But MacDonald was approaching 70 himself at the time (which even I admit is old, though I’m older than that now), and he was clearly experiencing intimations of mortality. There’s even a fleeting moment in this book, a sort of throwaway scene, where Trav acknowledges the possibility of the Great Beyond sending us messages.
The Lonely Silver Rain may not be the top entry in the Travis McGee series, but it’s written with all the skill and craft of a consummate professional. Plus, as a special bonus, there’s an episode at the end that adds a (possibly unintentional but touching ) coda that rounds out a classic detective series rather nicely.
