All My Enemies: a Brock and Kolla Mystery (Brock and Kolla Mysteries) 1st Pr of This edition

In one of the finest and most pivotal books in this critically acclaimed series, never before published in the U. S., D. S. Kathy Kolla reports to New Scotland Yard and to D. C. I. David Brock's Serious Crime Division. 
Just before Kolla is to start her new job, a young woman is found viscously murdered in a leafy, well-heeled suburb, and the grotesque details of the slaughter appear to be well-rehearsed, even theatrical.  Assigned to the case, Kolla's only improbable lead draws her to a local amateur drama group. Once in their orbit, she is lured into a piece of theatre over which, increasingly, she has little control. In All My Enemies, Brock and Kolla find themselves in a tangled web of deceptions in a case wherein a corpus of plays becomes a template for murder.
