In 2001, Brady wrote "The Gates of Janus", which was published by the US underground publisher Feral House. The book, Brady's analysis of serial murder and specific serial killers, sparked outrage when announced in the UK. According to Cowley, Brady regretted Hindley's imprisonment and the consequences of their actions, but not necessarily the crimes themselves. He saw no point in making any kind of public apology; instead, he "expresse remorse through actions". Twenty years of transcribing classical texts into braille came to an end when the authorities confiscated Brady's translation machine, for fear it might be used as a weapon. He once offered to donate one of his kidneys to "someone, anyone who needed one", but was blocked from doing so. According to Wilson, "it was because these attempts to express remorse were thrown back at him that he began to contemplate suicide". In 2006 officials intercepted 50 paracetamol pills hidden inside a hollowed-out crime novel sent to Brady by a female friend.
