You are a fan of the detective genre and you like to, with bated breath, follow the adventures of brave and resourceful detectives on the heels of pursuing bandits. What if the criminal is a maniacal killer who rapes girls and keeps the population of all the surrounding villages in fear? It seems that this will not surprise anyone now - many media outlets exaggerate such topics every day. But J. Wombo, the author of the book “On the Trail of Blood,” will certainly surprise the reader. Maybe because he himself worked as an investigator for many years and knows all the intricacies of the case of the rapist and murderer Colin Pitchfork, which shocked England in the 1980s? Or maybe due to his literary talent, thanks to which the terrible atrocities of the maniac appear so visibly before the reader that they make him nervously squeeze into his chair and feel real horror, which the spectacle of a criminal television chronicle cannot cause.
