MANY people around the world have a morbid fascination with serial killers.

There are countless books, films and TV series which focus on them, whether based on real people or fictitious characters.

The World's Worst Serial Killers is an interesting talk which runs through a list of 20 serial killers, detailing their crimes, their victims and also the occasional failings of the police in apprehending the perpetrators.

The talk is presented by Trevor Marriott, a retired murder squad detective, who talks clearly and in depth about some of the better known serial killers, such as Ted Bundy and Peter Sutcliffe, as well as some less well-known monsters, such as Andrei Chikatilo.

Anyone who is especially easily scared will probably not attend a talk on serial killers, but even those who aren't so sensitive will probably be shocked by some of the contents of the talk.

The audience are shown real crime scene pictures from some of the crimes, as well as gory photographs of some of the victims and interviews with the serial killers. This is certainly not for the faint-hearted, but there is a warning on Mr Marriott's website.

Mr Marriott is obviously a man who knows his stuff, and he talks seamlessly for just over two hours with hardly a prompt needed.

While each of the 20 serial killers and their crimes are introduced and described, the victims and the impact the crimes have on their families is not forgotten or lost in the show.

Huntingdon Hall in Worcester made for an atmospheric and intimate venue, and the show is a must for anyone who wants to learn more about some of the crimes that shook the world.
