Dark Heart

Most of this is a workmanlike unspooling of a mysterious series of killings. The victims are all men who were accused of sexually abusing children but whose cases were not brought to trial. Links are found to a killing which took place two years ago, but the man who did that confessed and is in prison. He was father to the abused child. But parents of the children abused by those targeted in the latest round all have alibis. Helped by some very good performances, notably by the lead actor, the riddle is unwound.. But the narrative is confused by a scene which seems pointlessly confusing inserted for no apparent reason.
