At 3 am on 15 November the body of a young private soldier, Peter Adams, was found 25 kilometres south of Darlington, beside the railway line from Edinburgh to London. He was absent without leave from his army base where he was due to face a disciplinary hearing. A wallet found on his person contained a small sum of money, a family photograph, an identity card, an out-of-date service railcard and a single railway ticket from Edinburgh to Peterborough. It is also known that: The private had been drinking heavily and arguing with a fellow soldier, Mike Finnegan, in the buffet at Edinburgh station at 9.30 pm on 14 November.
