Overdose

Dr. Emily Morrison undertakes a controversial drug study over protests from fringe groups and even some colleagues. Soon she’s facing death threats and a letter bomb that maims her secretary. Then a young coed suddenly dies after taking the experimental medication. Emily figures out what killed the girl—not the study drug but DIFP, a toxic chemical from her lab. A diabetic, Emily discovers the same toxin in her insulin. But when the police find a bottle of DIFP in Emily’s office, she suddenly changes from victim to suspect.

Then a professional killer comes after her, and he eliminates anyone who gets in the way. Emily knows she must confront this stalker on her terms, but she’ll have to do it without help, using only the element of surprise. And that’s just her first step in uncovering the truth – she needs to find out who hired the killer before someone else tries to finish what he started.
