Pill-making machines and a pair of glasses thought to have belonged to notorious poisoner Dr Crippen are to go under the hammer in Northamptonshire next week.

Northamptonshire-based auction house JP Humbert is also offering poison bottles recovered from the workplace of Hawley Harvey Crippen, who was hanged at London's Pentonville Prison in 1910 for murdering his wife, Cora.

A brooch thought to have been owned by Cora is also on sale at the auction in Towcester on November 19.

Crippen, who was born in the United States, is believed to have used hyoscine to kill Cora at his London home before attempting to flee to Canada.

Commenting ahead of the sale, auctioneer Jonathan Humbert predicted that the lots may emulate the success of other recently-sold items linked to well-known criminal names.

"The items were removed from Crippen's work address at Albion House, New Oxford Street, where he was medical advisor to a dental practice," Mr Humbert said.

"Whilst crime doesn't pay, people are paying large sums of money for crime-related items."
