In this novel Jonathan Kellerman bases his story outside of his usual territory of California but still with Alex and Robin Delaware. (Milo Sturgis, Alex's detective friend, makes "an appearance" by telephone but is in my opinion greatly missed.) The plot is based entirely on the tropical island and quickly gets going with action and character sub-plots. It was easy to get a visual picture and I could well imagine this becoming a film-plot. The enigmatic professor, that runs the island as a benevolent patriarch figure, is clearly disturbed and has an agenda which he only reveals bit by bit to Alex. Which I found makes the reader turn the pages quickly. I determined the characters either to be hateful or bland which was a bit of a disappointment but all in all I do not regret reading to the end.
