Heat lightning. John Sandford. 2009.

Homicide Detective Virgil Flowers doesn’t think much can surprise him any more. He’s wrong.

It’s a hot, humid night in Minnesota and Flowers is in bed with one of his ex-wives when the phone rings. It’s Lucas Davenport. There’s a body in Stillwater, two shots to the head - and a lemon in the victim’s mouth.

Exactly like the body they found last week.

The more Flowers works the murders, the more convinced he is that someone’s keeping a list - and that list could have a lot more names on it. If Flowers could only find out what connects them all……..But when he does start to piece the clues together, he realizes that this case leads down a lot more trails than he’d originally thought - and every one of them is booby-trapped.
