Dark Ambitions (Code of Honor, Bk. 3)

Former Army Night Stalker Rick Jordan usually has his camp for foster children to himself during the winter months. But someone has visited recently--leaving a trail of blood. One of the two clues left behind tips Rick off to the identity of his visitor, who soon turns up dead. The police deem it an accident, but Rick isn't convinced. With the help of private investigator Heather Shields, he sets out to decipher the remaining clue. Except someone doesn't want them to succeed--and will stop at nothing to keep them from finding the truth.
