Galway Private Investigator Jack Taylor is hired by the daughter of a former inmate of the infamous Magdalen Laundries to find the identity of a former nun, known only as Lucifer, who was notorious for taking pleasure in torturing the girls.
Jack has hardly begun his inquiries when he is warned off by local hard man Bill Cassell. He soon unearths evidence of a cover-up when files which might have revealed the nun’s identity are found to be missing from church records.
The case grows more complicated when Lucifer’s nephews are found executed –who is trying to get at her nearest and dearest? Matters get worse for Jack when he accidentally causes the death of Bill Cassell’s henchman.
Jack is now wanted not only by the Garda for his involvement in the henchman’s death, but also by
Bill Casssell. He faces a race against time to prevent a third murder, while at the same time the inevitable showdown with Bill grows ever nearer.
