DCS Frankie Sheehan does not wish to linger on the grisly scene before her eyes.

Two mutilated corpses. In a church. Meanwhile, a 17-year-old case is playing out on a TV documentary, historical police errors are being exposed daily.

Frankie's superior, commissioner Donna Hegarty, makes no bones about who she expects to clean things up in both cases . . .

But Frankie pinpoints just what is making her so nervous: the fact that anyone could be the next victim when justice is the killer.
