I've read all the DeMille I can get my hands on, and this one was one of my favorites. It's the first book in a set of two, The Lion's Game as its companion book (and which is a smidge better than this one, even!).
I like DeMille because at his best, his characters are smart and sassy, and the stories are cohesive, with serious subject matter presented with a touch of the absurd; the seriousness doesn't become so grave so as to obliterate any enjoyment of the story or his use of words. This story exemplifies exactly what I mean... once you begin reading, it's like riding over rapids. The water just rushes on, makes you laugh, and occasionally you stop, startled, when something bumps a bit more than you expected.
In this particular story, our main character (NYC investigator Paul Corey) is recovering on Long Island from some gunshot wounds, and he gets involved in the local double homicide of two scientists who work on Plum Island, a contagious disease research center right off of the coast. Of course, Paul is (in his own mind at least) smarter and savvier than any of the local yokels, even the pretty detective Beth Penrose, who's in charge of the investigation (although properly, she's not local, either).
The fact that the scientists worked with some of the most lethal pathogens on earth rises all sorts of speculation that they were being evil and subversive to assist some less-friendly nation with the wiping out of the human race, but Corey in all his infinite and dubious wisdom, uncovers an alternative theory that's much less lethal -- at least for greater mankind -- but all the more intriguing for those who love history and treasure hunts.
I enjoyed this book. Most voracious readers would, too.
