Private Prodigy Eye

Private Prodigy EyeThree Books in OneDead is the New AliveSylvie Thomas, 33, gets her chance at detective work when she hires on as assistant P. I. to Adam Clay, a 15-year-old genius. Though she carries the gun and drives the car, her real job is to keep him from winding up over someone's knee since he irritates almost everyone he meets. When they hire a young man to act as Adam at an award ceremony, someone kills the stand-in Adam.
Sylvie and Adam must help catch his own murderer. Adam's father is shot by a perhaps related sniper shooting before Adam can get back to Dukes County, TX. Blocked by an acting sheriff from helping with the investigation, Adam has to go vigilante and learn to cooperate with others. With a predator on the loose and few clues to follow, Adam and Sylvie know that at any moment they may themselves end up in the killer's crosshairs.
She Had Me at HelloAdam Clay's one redeeming feature has been his cold logic, and reclusive ways, but now his interest in gourmet cooking and a contest run by a dimple-cheeked female host of a cooking show combine with his budding hormones to lure him out into the open, only to have one of the judges drop dead. The recipe was for murder. Sylvie must contend with Adam's sudden interest in the other gender as well as a murder in her own Texas hometown.
Death Wears Cowgirl SpursAdam Clay has often told Sylvie Thomas that nature is something that belongs outdoors. He is far from a happy wrangler when they go to a dude ranch to ride horses across damp and muddy fields after a night of rain. When they come across the body of one of the ranch's hands, an airfield out at the far corner of the property, and discover the neighbors to the south acting more than a little on the prod, they decide there's a whole lot of something going on here.
They just don't know what. They also find out that someone wants them to find out no more than they already have, and is willing to kill to make their poking stop.
