The Killings — Clark Howard

Two LAPD detectives are at odds over a horrifying case in this “taut shocker” of a novel by an Edgar Award�"winning author (The Boston Globe).
 
A pair of twins have been brutally murdered, and Los Angeles detectives George Cascade and Ed Fenner find themselves working a case with puzzling sexual overtones. When a young, intellectually disabled African American becomes the object of suspicion, tensions flare between the two officers -- and it will push them to the edge before the truth can be sorted out.
 
“The kind of book you read at the point of a switchblade -- seemingly faster than you can turn the pages.” -- Kirkus Reviews
