In San Francisco, Parnassus Medical Group CEO Tim Markham is a victim
of a hit and run accident. Tim dies in his companyís Portola Hospital,
but the autopsy reveals that his injuries did not kill him. Instead Tim
died from an overdose of potassium. San Francisco homicide detective Abe
Glitsky believes that the doctor of record Eric Kensing killed his boss
because Tim was having an affair with the prime suspectís wife and the
HMOís cost-cutting measures threatened the lives of his patients. Attorney
Dismas Hardy thinks someone else is the killer. Soon evidence surfaces
that a serial killer has made the CEO victim number twelve. Now the two
best friends, Dismas and Abe, work on uncovering the identity of a murderer
before the toll reaches a bakerís dozen.
