June & Jennifer Gibbons were born April 11,1963 and grew up in Wales. They became the subject of books as "The Silent Twins" due to their choice to communicate only with each other, in their own language. They wrote brilliant works of fiction but were convicted of arson, and were committed to Broadmoor Hospital for 11 years. Prior to their release in 1993, they informed the CEO that Jennifer would have to die, "to allow June to be free." On that very day, Jennifer died suddenly at aged 29.
Broadmoor Hospital is a high-security psychiatric hospital at Crowthorne in the Borough of Bracknell Forest in Berkshire, England. It is the best known of the three high-security psychiatric hospitals in England, the other two being Ashworth and Rampton. Scotland has a similar institution at Carstairs, officially known as The State Hospital but often called Carstairs Hospital, which serves Scotland and Northern Ireland.
