The sad story of an uncaught serial killer who first murdered a 6 year-old girl, then 7 years later murdered a 7-year-old girl inside Barbican Station! Your Guide, Declan, discusses the similarities between the cases and profiles the Killer.

The sinister economics of dead people. Grave-robbing and serial killing. Clue: The Doctors at St Bartholomew’s Hospital were happy to deal with real low-lifes.

The most famous court in the world: The Central Criminal Court. Otherwise known as The Old Bailey. Two serial killers who had their trials here. Firstly, one who appeared here TWICE and who sent an innocent man to his death before later confessing his multiple murders of women. Then the grim background to another who murdered 13 women and caused terror for over FIVE years. Later in the Tour I talk about two other serial killers whose trials were here. One who murdered 15 boys and men; and the other serial killer who is perhaps the most dangerous woman in the world.

A ‘lighter’ moment on the Tour… Declan wants your vote on the scariest horror movies of all time. Declan reveals the 'Top Ten' votes from 23 years of the Tour, including a film in the 'Top Ten' that most of you simply do not know. Even more intriguingly, the film has been recommended by 2,000 men, but not one single woman! Also Declan's personal recommendation: a total cult classic horror film, 60 years old, that practically none of you will have seen. And it's free to watch on YouTube.

Hear a dramatic, immersive account of a little known Victorian serial killer who murdered on two continents and lived here. This true-life story, with a number of twists, would be perfect for a Movie, and yet the Movie has never been made. The story ends with a question, based on what you will have just heard, which very, very few people can get right...

It's Jack the Ripper time. We visit the place, just off Fleet Street, where my Jack the Ripper suspect lived, and hear a detailed account of precisely why I think this man was Jack the Ripper. (He has an entire chapter in my 'Bloody London' book. Let's see how good you are at profiling... Also In this Jack the Ripper section of the tour is the toughest question of the entire tour. Get this particular question right and you are on the 'Roll of Honour' of 'The Blood and Tears Walk'. Only one person out of every 500 people who attends the Tour can get this question right!

The narrow, dingy, isolated alley we enter here may just be the creepiest place you have been to in your entire life. And I am not kidding... We conduct a psychic experiment here - it's a murder scene - and you hear about a pair of devious serial killers who operated around here. If you are psychic, you will NOT like this place. I have had tough men be shaken by the atmosphere in here, especially in the dark months. Warning: This is NOT a nice place. And you will feel it.

This is your section. I am not going to spoil what that means, but it is unfailingly interesting, and sometimes mind-boggling and jaw-dropping.

I mentioned them earlier. These are two other serial killers whose trials were at the Central Criminal Court. One who murdered 15 boys and men. The other serial killer may well be the most dangerous woman in the world.

We end at the wonderful Princess Louise pub, famous for its wonderful Victorian decor. However, after the final serial killer story of the Tour, you may hesitate to enter this pub! I will tell you about a well-known British serial killer's truly horrible piece of behaviour. I can guarantee that you simply won't know of this, despite all the books and documentaries about this person. What I will tell you isn't in those books and documentaries. How do I know the information? Because it was told to me by the Head of Forensics involved in the case of this serial killer. He came on my Tour! After this final story, Declan will sell copies of his best-selling book 'Bloody London' for £10 cash or Paypal. Declan signs each book with a personal message.
