On the surface, David Baddiel’s childhood was fairly standard. But David came to realise that his mother was in fact not ordinary at all. Having escaped extermination by fleeing Nazi Germany as a child, she was desperate to make her life count, which took the form of a passionate, decades-long affair with a golfing memorabilia salesman. David’s detailing of the affair – including a hilarious focus on how his mother turned their household over to golf memorabilia, and an eye-popping cache of her erotic writings – leads to the inescapable conclusion that Sarah Baddiel was a cross between Jack Niklaus and Erica Jong. Meanwhile, as Baddiel investigates his family’s past, his father’s memories are fading; dementia is making him moodier and more disinhibited, with an even greater penchant for obscenity. As with his mother’s affair, there is both comedy and poignancy to be found.
