Tom Sanders is a celebrated writer of self-help books. His bestsellers “Crime Without Frontiers” and “Easy Living” have sold more than forty million copies worldwide. He leads an extremely comfortable life, is happily married to Julia, and has two grown-up sons, the youngest of whom, Stefan, is the apple of his eye. Suddenly, during a birthday party for Julia, their daughter-in-law Hanna – of whom Tom and Julia are not particularly fond – turns up at the door. Sobbing, she says that Stefan has beaten her and that this is not the first time. Should Tom tackle his favourite son about his behaviour? Or would it perhaps be better to put the advice from his self-help books into practice, such as his famous precept ‘Try not to solve problems by thinking about them; often they are sooner solved by not thinking about them’?
