Death Illuminated

The past deciphers the future.

After making wrong decisions with his first murder investigation, Detective Matthew Compton is glad to still have his position as sergeant. Now he has a string of assaults on prostitutes, and his only lead: cryptic lines from a Medieval book of the dead.
Even though DS Compton saved his life in his previous case, Detective Inspector Jacob Murray needs someone less complicated as his second. Now he has a new sergeant, multiple murders, and clues written in a language he can't decipher.
At first the cases appear unrelated, but as the detectives follow the clues, they find their cases become intertwined on both a criminal and personal level.
Will they be able to put aside past differences to stop a killer before someone close to them becomes the next victim?
