I don't want to start a new thread so put this here as I'm not sure where to put it.
I'm off this week, my wife was at work so I watched a documentary on the history of Broadmoor whilst ironing (I'm so rock and roll). I was interested in the story of the Silent Twins that I hadn't heard of before. According to the documentary, when they were eventually released, they decided that one of them must die. According to the documentary, one of them died in the transport releasing them from Broadmoor, the cause of death not ascertained. This may be factually incorrect as I was ironing at the time.
I found this book on Amazon that I may well buy as it looks quite interesting:
The Silent Twins eBook: Wallace, Marjorie: Amazon.co.uk: Kindle Store
