In Their Blood

At the start of Potts's debut, a red-hot suspense novel, a midnight intruder murders D.C. Stroeb, an economics professor at Miami Intercontinental University, and his CPA wife, Rachel, in their exclusive Lotus Island, Fla., estate. Oddly, the killer takes only the couple's laptops. Their 16-year-old daughter, Elise, who was home at the time, suffers emotional trauma in the aftermath. Their 22-year-old son, Jeremy, who can't believe anyone could kill his parents, returns from backpacking abroad to assume the guardianship of Elise, against the wishes of his lawyer uncle, Dwight Stroeb. Jeremy connects with a sympathetic Miami detective, gets a job at his mother's CPA firm and enrolls at his father's university, where he becomes involved with his father's female graduate assistant, a Peruvian-French sexpot. The clue hunt sizzles in a plot driven largely by shifty accounting. By the end, the dangers of creative number crunching are all too apparent. (Sept.)
