Already dubbed the most believable time travel adventure ever written, this is the first instalment of the Sixty-Six trilogy. Have you ever felt uneasy when alone? Or sensed a presence you can't explain? Simon Benson has. Air-conditioning engineer Simon is single and dissatisfied with life, so when his student inventor friends John and Emily ask for help with their Human Aspect Scanner - a machine that captures glimpses of the past through harnessing powerful residual energy - Simon jumps at the chance. At first the trio revel in their discoveries, snooping around Durham's historical streets, but they soon realise that some events of the past are better left unseen. When they unearth an inexplicable old photo of Simon, enjoying life in 1912, they discover they've created more mysteries than they've solved. For Simon, however, there are only two questions he wants answering... Who is the beautiful girl kissing him in the photo, and will he ever meet her?
