'On Her Majesty's Secret Service' (1963) by Ian Fleming

'On Her Majesty's Secret Service' is the tenth novel and eleventh book in Ian Fleming's James Bond series. Fleming changed the formula and structure from the previous novel, The Spy Who Loved Me (that was not well received), and made a determined effort to produce a work that adhered to his tried and tested format.

On Her Majesty's Secret Service is the second book in what is known as the "Blofeld trilogy", which begins with Thunderball and concludes with You Only Live Twice. This episode centres on Bond's ongoing search to find Ernst Stavro Blofeld after the Thunderball incident. Bond finds Blofeld in Switzerland and attacks the centre where he is based, although Blofeld escapes in the confusion. Bond meets and falls in love with Contessa Teresa "Tracy" di Vicenzo during the story. The pair marry at the end of the novel, but hours after the ceremony, Blofeld and his partner, Irma Bunt, attack the couple and Tracy is killed. Fleming developed Bond's character within the book, showing an emotional side that was not present in the previous stories.
