Hidden away on the first floor of New Scotland Yard in Central London, is a museum not usually open to the public. For 130 years the crime museum has quietly archived the tools, relics and instruments of killers, conmen and thieves.

Now it is opened by invitation only and we have been granted access to film inside the museum for this fascinating and revealing 13-part series. Presented by one of Britain’s most experienced broadcasters, Nick Ross, the series will give viewers exclusive access to the world’s oldest museum of crime.

Grisly exhibits, as used in evidence, are revealed for the first time. Using dramatic reconstruction, expert testimony and with the help of these gruesome artefacts, the stories of London’s most iconic crimes and criminals are brought to life like never before.

This episode is the case of Dr Hawley Harvey Crippen who apparently murdered his wife in 1910 and was then chased across the world. Though some now doubt his conviction, several locks of hair and Mrs Cora Crippen’s pyjamas are discussed.
