Broadmoor Sinister is a must-read for everyone with an interest in homicidal insanity, serial murder and the true meaning of evil.

Boris Coster is perhaps the world’s leading authority on what was previously known as the ‘Broadmoor Criminal Lunatic Asylum’. His depth of research into the history, beginning in the middle 1800s, of what we might call ‘The Mother of all British Asylums’, brings to the reader its remarkable 157-year history - the good and bad times, and its terrifying times - to its closure when the Commission for Healthcare Improvement declared it unfit for purpose in 2003.

This so-called ‘high-security facility’, Broadmoor, has housed and treated some of the most notoriously evil, mentally deranged killers in the black annals of British criminal history. Yet, while the majority were safely incarcerated behind the grim walls and glistening wire, others were freed to kill again and again, to terrorise communities, most shockingly with no accountability at all.

Sunday Times bestselling author, Christopher Berry-Dee brings to Broadmoor Sinister his own unique talents: psychopathological studies of the killers – from Ronnie Kray to Peter Sutcliffe and Charles Bronson - and comparisons with other notorious overseas mass murderers and serial killers, taking the reader inside the heads of these monsters.
