Requiem Mass

The first deaths are just a warm-up...
A Buried Past.
When Deborah Fearnside, a young wife and mother, goes missing, police interest is minimal. She would hardly be the first woman to abandon a tired marriage. Four weeks later it is Detective Chief Inspector Andrew Fenwick, back from compassionate leave, who notices the set of coincidences that should have transformed a routine missing person's case into a suspected abduction. But by then it is too late for Debbie.
A Dark Secret.
Twenty years ago, a young woman fell tragically to her death. The only people with her were four schoolfriends. One—or maybe all of them—is responsible. Now there's someone intent on letting them have their just deserts.
A Bloody Revenge.
Fenwick is soon caught in a desperate race against time to find the murderer before he completes his brutal vendetta. As the death toll mounts, Fenwick stares failure in the face—unless he can draw the predator out of the shadows and into an unconventional and highly dangerous trap with the ultimate bait in Requiem Mass, a chilling Sussex mystery from Elizabeth Corley.
Praise for Requiem Mass:
"These characters are well drawn, especially Fenwick, and even the killer avoids cliché. Boasting a very tense, superb ending, this second in a gritty new series (following Fatal Legacy, 2001) shows tremendous promise and is sure to appeal to fans of Tana French, Benjamin Black, and Tess Gerritsen." —Booklist
