Happy Birthday, Mr Chizlehurst

Rosie and Wilmot are called to the house of argumentative Councillor Blake after a duck has flown in through his bedroom window and got stuck under the bed. Annoyed by the councillor's high-handed attitude Rosie scares him by claiming it is an exploding duck before rescuing the bird. In the evening Rosie and his family attend Bill's birthday party. WPC Whatmough is also there and far from pleased to see that Wilmot has brought his buxom cleaner Winnie along as his guest.
