Nick Chambers QC, who lives in Chipping Norton, is a civil court judge and has spent his working life sitting in court. He is also a sixth-generation watercolourist and met his wife Sally at the Ruskin School of Drawing in Oxford.

His book, Missed Moments in Legal History (Oblong, £19.95), was inspired by the tale of Mrs Donoghue, who found a decomposed snail in a bottle of ginger beer and made legal history.

It is a case well known to law students, but Mr Chambers’s picture shows an alternative scenario — Mrs Donoghue spending a pleasantly uneventful afternoon in Paisley, consuming ice cream and snail-less ginger beer. The text, meanwhile, also tells you what did happen so that you can understand the pictures of what might have happened.
