Martin and Ann meet their new neighbour Paul. Ann believes that he will be a welcome addition to the Close, but Martin is not so sure.

Martin and certain others in the Close are nearly scandalized by Paul's outlandish behavior. Burning perfectly good house signs? Entertaining scantily clad women in his back garden? What is all this?

It's time for members of the Close to go on a holiday outing, and some wish to repeat an earlier trip to the Bavarian Alps. But Paul has something altogether different in mind. Will Ann and the rest like it?

Martin organizes a fund-raising dance. Paul innocently lends a helping hand, and in doing so mercilessly interferes with Martin's arrangements. How will Martin retaliate?
