The Island of Sheep is the fifth, last and most unusual of the Hannay books. Having returned once again to a quiet life at Fosse Manor, Hannay’s life is shaken a final time when the son of an old acquaintance from Africa asks for his help in finishing a feud that goes back thirty years to a hilltop in Rhodesia. Hannay sets out to protect the family - a trip that takes him from the England he knows to the Norlands, the Island of Sheep of the title (loosely based on the Faroe Islands where Buchan holidayed and wrote the book).
