Blood Poison — D.H. Dublin

In the Philadelphia Police Department, the Crime Scene Unit takes blood, sweat, tears-and other DNA samples.

The death-by-overdose of Derek Grant, environmentalist and vegetarian, comes as a shock to almost everyone. His distraught, wheelchair-bound father, Horace, who found the corpse, wonders how Derek could do this. And the more rookie forensics detective Madison Cross investigates, the less his death makes any sense. But as she entangles herself in the web of their perverse family, Madison realizes, to her horror, that the killer is honing in on her.
