The 5th Horseman

From bestselling author James Patterson, the Women’s Murder Club takes on a string of mysterious patient murders at a hospital–will they find the killer before more innocent lives are lost?
 
It is a wild race against time as Lieutenant Lindsay Boxer and the newest member of the Women's Murder Club, attorney Yuki Castellano, lead an investigation against a hospital administration determined to shield its reputation at all costs. And while the hospital wages an explosive court battle that grips the entire nation, the Women's Murder Club hunts for a merciless killer–who just might be one of the medical staff.
 
With high-speed thrills and page-turning twists, The 5th Horseman proves once again that James Patterson "has mastered the art of writing" (Chicago Sun-Times).
