The Unseen - Chase Dagger, #3

Chase Dagger is pulled into several cases that are linked by the most bizarre common denominator: Not one surveillance camera reveals the assailant. Sergeant Padre Martinez believes the assailant is an old nemesis, a computer savvy ex-con who has manipulated cameras in the past. When the body of a research scientist and his wife are discovered, things get complicated. Not only are the ex-con's prints found in the scientist's home, but the deaths also attract the interest of the FBI, CIA, NSA, and DOD.
Exactly what was the scientist working on and what connection does he have to the other cases? Are the crimes really the skill of a high-tech genius or is there something more sinister at work? Just when the evidence points strongly to Padre's number one suspect, Padre is accused of planting evidence and removed from the case. Enter Chase Dagger. Unusual cases require unusual detectives. Whether it's solving the case of a woman who is murdered five years aftr her alleged death (THE GOOD DIE TWICE) or chasing after a suspect not quite human (FULL MOON-BLOODY MOON), Dagger has his hands full while staying two steps ahead of his mysterious past.
