The Last Book of Hugo Madariaga

Forty-three letters, sealed in an iron strongbox beneath a bookshop counter, carry a warning in his dead father's hand: do not let Salmerón find them. Nicolás Olmeda came back to Granada only to sell the shop and leave. Instead he finds a love story buried in the Civil War, a novelist the world believes is dead, and a ruthless dealer determined to burn the truth. To honour one promise, Nicolás must break every plan he had for his life.
