Acclaimed author Trevor Marriott is coming to the Towngate Theatre in Basildon with his show, the World’s Worst Serial Killers.

The former murder squad detective will conduct a two-hour audiovisual presentation, which will delve into the chilling cold cases and murders committed by 20 of the world’s most notorious criminals.

Trevor, who is the author of the bestselling book, the Evil Within – the World’s Worst Serial Killers, has also conducted a detailed study about Jack the Ripper.

He said: “Not only do I portray the killers as the monsters they are, but I show the pain and suffering endured by not only the victims, but the relatives left behind.

“I also go to great lengths to highlight the errors and bad judgment calls made by law enforcement agencies in allowing some of these killers to go free and kill again before being finally incarcerated.”

The show features images of the victims and their killers, but also photographs from the crime scenes – many of which will never have been seen before.

As such, his show is not for the squeamish or fainthearted, as many of the images shown are of a very graphic nature, which some may find disturbing.

Anyone under 16 years will not be admitted without a parent or appropriate adult.

The show, on Wednesday, June 18, is at 7.30pm.

Tickets are £12 each, £10 concessions, which can be brought online at www.towngatetheatre.co.uk or by calling the box office on 01268 465465.
