The Man who Cleaned Gravestones

Why would a retired detective be cleaning gravestones? Bob Macinaly had to retire from the job he loved after having been shot by a bank robber. He had taken a holiday in Mallorca trying to get his life back together. By chance, he found himself in a Salvation Army charity shop and purchased a second-hand book. A letter hidden inside changed his life forever. As a police officer he moved from one case to another and very seldom could he follow up on the unseen victims left behind, namely the close families who would suffer forever whilst the convicted murderer would live out life in, some would say, comparative luxury. From now on this would be different; he would become close to human trafficking and the evil controllers and the crime lords making millions at the cost of human lives.
