Money

In the first episode, Henry attempts to help out Cath who is, like many young couples, struggling with astronomical rent rates (Made harder by her husband, Jeremy, enjoying a sabbatical teaching in Lesotho). Yet, when the Bank is far from helpful and the Letting Agent is unwilling to cut them some slack, Henry is forced to face the prospect of selling his house and downsizing to a retirement home. If that's the case, he isn't going to go quietly, so it falls to Margaret and Charles to come up with a rescue package.
