For Arthur Rowe the charity fete was a trip back to childhood, a welcome chance to escape the terror of the Blitz.
Then he correctly guesses the weight of a cake and from that moment - he's a hunted man.
A man wakes up in a clinic.
He's a civilian casualty and has lost his memory; apparently his name is Richard Digby.
The doctors don't want him to leave.
