Now comes Dr Bogle & Mrs Chandler ? the Confession in which Peter Butt delivers more intrigue, including the astonishing story of the person who covered the victims? bodies and how the prime suspect in the case, Geoffrey Chandler, was an undercover ASIO agent. The most sensational revelation - the explosive testimony of a retired psychologist concerning two previously unknown witnesses to the deaths.

It really is quite compelling isn't it? As I've pointed out before, every time you come up with something new, I try my hardest to disprove it'this time I'm having a real problem! When I told the coroner what you had sent me, she was captivated by this news. She also wondered out loud what she would do next'an inquest maybe? All I can say is that if what your new source says is true, then it pretty much means you've hit the nail on the head, and the mystery is finally solved, just over half a century after the event.'
