SPY thriller writer John le Carré left more than £17million in his will.
Le Carré, 89, died from pneumonia in December.
Figures released by the probate office in London show he left £17,921,184.
His wife Jane got £1million and a Sussex house.
But she died two months after him, aged 82.
Le Carré, who had four sons from two marriages, left £50,000 to each of his grandchildren with the bulk of the rest going to his adult kids.
Born David Cornwall in Poole, Dorset, in 1931, he worked for both MI5 and MI6 but left to become a full-time author.
The Spy Who Came In From The Cold — his third of more than two dozen books — launched him to literary success.
He also penned Tinker, Tailor, Soldier, Spy.
