Letters from two notorious murderers have sold at a Scottish auction for £600.
The writings by London gangster Reggie Kray and US cult leader Charles Manson sold for £200 and £400 respectively when they went under the hammer at McTear's Auctioneers in Glasgow.
The items were put up for sale by "murderabilia" collector and crime author Steven F Scouller, who believes the study of such material can give an insight into the criminal mind.
The letter from Reggie Kray, who terrorised the East End of London with his twin Ronnie in the 1950s and 60s, is a 20-page diary of ideas and orders for "Kray Firm" gang members to carry out. Mr Scouller said parts of the letter are written in code to prevent the authorities from intercepting the messages.
In the letter Kray writes: "Go to work for the fee. I'm so proud of all you've achieved." It is signed off at the bottom with "Take care, God bless, affection, yours Reg."
Hundreds of thousands of pounds have been spent at auctions across the UK on Kray memorabilia including photographs and paintings made by the brothers. Both of them were jailed in 1969 for 30 years, Ronnie Kray for the murder of George Cornell and Reggie for killing Jack "The Hat" McVitie. Ronnie died from a heart attack in Broadmoor top-security hospital in 1995 and Reggie died in 2000 from cancer.
Manson remains in Corcoran State Prison in California at the age of 77. He has also been in jail since 1969 after he orchestrated a series of gruesome murders on consecutive nights in Los Angeles.
McTear's said his letter is "incoherent" but seems to discuss his relationship with other cult members.
Manson writes: "It can be used as the people in the so-called Family used me; by giving me their problems...all I did was give them the answers...You see them singing my music and dancing my motions. That's how I've survived all my life by staying on top of my end."
Managing director of McTear's Brian Clements said: "These are very unusual items that give an insight into the minds of two of the world's most notorious criminals. It is rare to find detailed letters like these coming to auction and as such there was a lot of interest in the sale."
