Having stayed at Bramble Lodge for one night, Sheldon heads for the exit door but Paul has other plans. He's found a friend and isn't about to let him go. He enlists Jean, the warden, and Sheldon becomes her special 'project'.

His reluctance disappears when she offers him £50 to do a few odd jobs around the place. And she goes one further: with the help of local copper Sergeant Swithenback, she decides Sheldon would make an excellent Special Constable. The training regime begins.

Gambling is against the rules at Bramble Lodge. Syd plans a poker game, although Dorothy is not invited to play because she always wins. Instead she holds Graham's cards and strangely enough, he seems to be on a winning streak.

Having stolen Sheldon's £50, and lost it at poker, Paul plans to expose the game to Jean in order to get out a tricky situation.
