Following on from the bestselling Inside Broadmoor and Inside Wakefield, Jonathan Levi and Emma French will deploy their trademark combination of exclusive access to prisoner testimony and staff revelations, weaving a compelling, unfiltered story examining the lives and crimes of Belmarsh Prison's most deadly and notorious prisoners. From exclusive revelations of the Hatton Garden gang, who smarted at the injustice of doing time alongside monstrous killers, to unique insights on inmates past and present including John Warboys, Ian Huntley, Jonathan Aitken, Michael Adebowale, Thomas Mair and Wayne Couzens. No prisoner has ever escaped...but some have certainly tried. Through fights, drugs, gangs and, sometimes, redemption, Emma and Jonathan will discover the truth about what it's like to live and work in 'Hellmarsh', Britain's toughest and most renowned prison.
