Want a light but not completely silly book for summer? Cheer Up, Mr. Widdicombe fits the bill. It stars a carefully composed set of characters, from the pater familias settling uncomfortably into retirement, his wife who is on a house decorating frenzy, their heartbroken and bored son, and assorted house visitors. Minor drams ensue.
I kep wondering why the wealthy couple employs a personal assistant (so fancy!) and a gardener (reasonable) but no housekeeper. It may be better to not think too much about such details.
