Heat Lightning

I haven't read the first Virgil Flowers book. This is the first one my library had, so that is where I started. Turns out this one stands alone well, but I reckon it is slightly spoilerish for the first book.
Anyway, I quite enjoyed Heat Lightning. It seems that someone is killing men execution style and leaving the bodies at veteran's memorials. Davenport is super busy; so, Virgil Flowers gets the call. Flowers moves in in his laid-back style, asking questions and generally shaking trees to see what falls out. It soon becomes apparent that the killings are very professional, and they are related somehow to an incident many years ago in Vietnam. Someone is on a vendetta.
Soon things get violent and deadly with plenty of action and gunplay, and with the killers always one step ahead. Flowers has has his work cut out both solving multiple mysteries and staying alive. The finish is both exciting and satisfactory.
Good crime fiction. Solid four stars.
