This novel by John Le Carré was published posthumously by his youngest son, Nick Cornwell, with--according to him--only minor editing required. It is a short but evocative story of the disillusionment of one former agent of MI6 who turns his back on country rather than on his ideals. Former City financier, Julian Lawndsley, has left the hustle and purchased a small book shop in an East Anglian seaside town, even though he knows absolutely nothing about the business. He is seemingly rescued by one of the town's residents, Edward Avon, who browses but doesn't buy, but offers up the idea of converting the basement to a literary haven, which would stock all the writers and philosophers who are not the usual bookshop fare. Edward, a Polish emigre, lives with his wife, who is dying of cancer, in the manse Silverview, just outside of town.
Meanwhile, when the head of security for MI6, Stewart Proctor, receives a note from a former agent warning of an intelligence leak, his queries lead him to this same quiet town and to Julian.
