Homicide detective Kay Delaney is back in her second book, partnered with Danny Finnerly (Finn) both at work and on a personal level. The couple ends up on the trail of a murderer who left a human heart on the grounds of an exclusive private school. As they begin to find connections to another murder that occurred a couple of months before, they become concerned about a serial killer.

BLUE VALOR is a tense police procedural-style of mystery that I thoroughly enjoyed. As a huge romance fan, I was a little upset watching Kay and Finn's romance fall apart and am curious to see where that aspect will go. But on the mystery/suspense level, Ms. Haus is not to be faulted. The glimpses into the killer's thoughts heighten the tension. There are several subplots, not the least of which is the personal story I mentioned, and certainly enough to entertain the most demanding of mystery readers. I certainly recommend this series -- and I'd start with the first one, BLUE MERCY.
