A new exhibition at the Museum of London reveals a bunch of stuff previously hidden from public view at Scotland Yard.
1. This is a "murder bag" – a forensics kit used by detectives attending crime scenes.
2. And these are the ropes that hanged London’s most notorious criminals.
3. But it's not as grisly as you think it's going to be. Sure, there are death masks, such as this one of Daniel Good.
4. And this one of Robert Marley, who bludgeoned the owner of a jewellery shop to death and was hanged for his crime in 1856.
5. And yes, these may be the rubber gloves of John Haigh, who dissolved his victims in acid baths in the 1940s.
6. But it's not all gruesome. This is a poster issued by the Metropolitan police in 1888, an appeal for information about Jack the Ripper.
7. This button and badge belonged to a man who might not have committed the crime he was jailed for in 1918 after all.
He was released after his 15-year sentence for the rape and murder of Nellie Trew, but always proclaimed his innocence despite his button and badge having been found at the crime scene.
8. Ronnie and Reggie Kray never used this syringe and poison to kill a witness at the Old Bailey in 1968.
9. These old cans were only used to smuggle drugs.
10. And this is shrapnel from a Fenian bomb that never exploded in Paddington Station, 1884.
11. The collection focuses on the weird humanness we forget about when we're reading about crimes.
Alongside cat burglar Charles Peace's fold-up ladder for breaking and entering, there's his violin. He was both a talented musician and a criminal, and was executed for killing a police officer in a burglary gone wrong in 1878.
