A fox makes its way across London's Waterloo Bridge. The distraction causes two pedestrians to collide - Jean, an American studying the habits of urban foxes, and Attila, a Ghanaian psychiatrist there to deliver a keynote speech. In this delicate tale of love and loss, of cruelty and kindness, Aminatta Forna asks us to consider the interconnectedness of lives, our co-existence with one another and all living creatures, and the true nature of happiness.
