A year after "Neil Dovestones" was found, the investigation has become truly multi-national, with links to Pakistan, the Netherlands and Slovakia.

With no idea who he is, the police have to rely on the small number of clues found in the man's pockets. From the remote moorland track where his body was found, they begin to retrace his steps. Can they discover where his journey started? And we meet the last person known to have talked to him before he died. With Jon Manel.

Last December a man's body was discovered in the desolate landscape of Saddleworth Moor in the Peak District National Park.

There was no clue as to who the man was. Six months on, he still hasn't been identified and his body remains in a mortuary in Oldham.

For months, those leading the investigation have been sharing their progress with Jon Manel.
