By now you know I’m a mystery reader. Love them! Especially if they are a series. And Jeffery Deaver writes some knockout plots. In The Stone Monkey (which has in my opinion the best secondary character in all his books), Lincoln Rhyme of The Bone Collector fame (Denzel Washington) once again schools his minions on evidence collection and analysis with his (in)famous bare bones and boiled down term, individuate. It’s a great read and vocabulary building makes a nice excuse for picking it up and immersing yourself in it.
