During Christmas 2012, 76 year old Patricia Goodband vanished without a trace. Pat’s business partner and friend Chris Symons said he’d dropped her off at Milton Keynes train station so that she could visit a friend in the North for New Year. The murderer tried to throw police off the scent by sending texts from her phone. Detectives hunting for clues of Pat’s whereabouts hoped to find their answer within her diaries. But it would be another piece of written evidence that would give them their biggest breakthrough.
