South America in the 1970s. A group of revolutionaries plan to highlight their cause by kidnapping the American ambassador. Unfortunately, they get it wrong and kidnap instead Charley Fortnum, a boozy expatriate Briton whose quasi-official status as an honorary consul amunts to little more than the right to import and sell a car every two years. Dr Plarr, one of only two other Britons in the city, is involved from the start: not only was it he who provided the revolutionaries with their information, but he is also having an affair with Fortnum's young wife. Though this is more sombre in tone than some of Greene's other 'entertainments', there is much wry humour in these pages, but what struck me most was the degree of emotional involvement Greene manages to produce in what could easily have been a cynical tale of unprincipled behaviour and bungling. The novel takes us down a dark road, and I found some of the later scenes really quite sad, but I hope I'm not giving too much away by saying that the road leads eventually to redemption - of a kind.
