My first thought was to say 4 but I couldn't easily put it down, so that's a 5 isn't it? Settled at 4.5. Nap for Napoleon Dumas, a police detective in a small New Jersey city, still "talks" to his twin brother Leo who died in an apparent suicide with his girl friend Diane 15 years ago. Nap's own special, Maura, the love of his 18 year-old life, disappeared at the same time without saying a word of goodbye. Nap has looked for her during those 15 years with little to show for it, and then her fingerprints are found at the scene of a cop killing. When the officer turns out to have been a member of Leo's strange club along with Maura, Nap realizes he's onto something. What did happen to Leo? A delicious chase and a terrific surprise awaits. My first Coben and far from my last.
