A child buried alive.
Three lawyers battered to death.
A judge murdered in his own home.
DCI Sheehan and his Serious Crimes Unit investigate the murders of the three solicitors. Revelations about the victims' shady dealings offer Sheehan and his Serious Crimes Unit a large number of solid suspects.

Yet one suspect stands out above the others.

Evidence piles up against a grieving mother who is convinced the lawyers are behind the death of her nine-year-old daughter. The team is convinced they have their killer.

But DCI Sheehan isn't so sure.

When a fourth victim is murdered, he is forced to look at the entire investigation with fresh eyes.
Is the evidence against the key suspect as solid as it appears? A dark figure in the background resents Sheehan's interference and when Sheehan's enquiries seem to exonerate the mother, events escalate to an explosive climax.
