James Patterson and Maxine Paetro. The 5th Horseman (2006) 410 pp.
Keiko, the mother of the newest member of the Women’s Murder Club, attorney Yuki Castellano, collapses and is rushed to San Francisco Municipal Hospital. Apparently, Keiko has had a Transient Ischemic Attack, but seems to be recovering. After accompanying Yuki to the hospital, police detective Lindsay Boxer goes home only to learn later that Keiko suddenly and unexpectedly died. A stunned Lindsay soon learns that the municipal hospital has been a place where too many recent deaths have occurred due to incorrect medication given to patients. Keiko apparently is the latest lethal mistake. Lindsay thinks a warped “angel” of not mercy is killing people just prior to their leaving the hospital. Though her plate is filled with an investigation into the “Car Girls” serial murders, she vows with the help of her Women’s Murder Club members to take down the hospital killer.
