Predator in the House by Joanne C. Parsons

Boston Police Sex Crimes Unit Detective, Karl Shea, stumbles and falls on the eve of his retirement. Blaming himself for the death of a child, he kills local sex offenders to avenge her death.
When he learns he is terminally ill, he changes focus and searches for an abducted young girl.
Karl races against time, and stays one step ahead of his duplicitous wife, the police, and cancer, as he explores the dark world of child sex trafficking and finds a road leading him close to home.
Predator in the House is not a dark, grim story. It is at once intriguing and entertaining, as readers search for the rat in this cat and mouse game.
