Dead Past. Number 4 in series

Diane Fallon's crime scene unit is facing one of its worst ever cases: an explosion in a converted house has claimed many lives - from the students attending a party in one of the upstairs apartments to the junkies running a meth lab in the basement. Diane and her team will be sifting the evidence for days, searching the scene for any slight clue to the identities of the unrecognisable bodies. The incident has a devastating impact on the local community - with most people knowing at least one of the victims.
One of the party survivors was even a member of Diane's staff - lucky enough to escape with her life. Diane is determined to discover the root cause of the explosion. But she must do so while avoiding the frenzy of media interest, local government officials keen to assign blame and the political machinations of a chief fire inspector who will stop at nothing to get Diane's job.
