"The Time Detective - Book 1 - Discovery" by Mark Carnelley is a quite a disturbing serial killer book with an ingenious storyline involving time travel, that although looks like it may be suitable for younger readers it is most definitely an adult read, due to the violent and sexual content.
The story follows Marshall Bellows, a Police Officer here in the present who, during the chase for a sick, serial killer discovers a wormhole that allows him to travel back into 1956, where he takes on the persona of Allan Besley. He is a crime fighter in two times, two different worlds.
Although an open mind is needed for this story I did find it hugely entertaining, however, some readers may find the level of violence towards the young girls distressing so if easily offended then this book may not be for you. I do like my serial killers to be sick and twisted and enjoyed how the story crossed over into the two different timelines.
Marshall Bellows/Allan Beasley is a brilliant character and a superb police officer and the way the author has created a unique and well plotted story has resulted in an excellently written, entertaining and compelling crime novel that's well worth a read!
