As part of the cases described in this book, its author, Mark Williams-Thomas, will explain in detail how, while searching for suspects, he finds connections between leads. He will tell you about the tools at his disposal that allow you to comb the most hidden corners. When Mark joined the police, he was only 19 years old, and he thought that he would devote his whole life to this, but at the age of 31 he decided to change his field of activity. By luck, he got into television as a consultant to the writer of a crime show. Mark was so good at his job that he soon began consulting with the writers of almost all the crime shows that aired on the two major British channels. After some time, he changed his profession again and became an investigative journalist, which he still works as. So relatives of killed or missing people who had not received help from the police began to contact him.
