Roy Southgate and Reginald Conynghame-Jervis have nothing in common but their loneliness and their wartime memories.Roy, a retired milkman and Reggie, a former RAF Squadron Leader, are widowed on the same day. To assuage their grief, the vicar arranges for Roy to move in with Reggie as his unpaid manservant. To their surprise, they form a strange alliance, based on obedience, need and the strangeness of single life. Then Reggie meets Liz, a vibrant but near-bankrupt woman of irresistible appeal, while Roy and his sons family grow gradually closer. Marriage, it seems, however far from ideal, can be a great protector against isolation.
