On Her Majesty's Secret Service (
While searching for Ernst Stavro Blofeld, the head of SPECTRE, Bond saves Tracy di Vicenzo on the beach from committing suicide by drowning, and later meets her again in a casino. Bond then receives information from Marc-Ange Draco, the head of the European crime syndicate Unione Corse and Tracy's father, about Blofeld's Swiss solicitor. Bond breaks into the solicitors office and establishes Blofeld is corresponding with the London College of Arms. Posing as an emissary of the college, Bond meets Blofeld, who has established a clinical allergy-research institute atop Piz Gloria in the Swiss Alps. Bond soon establishes that Blofeld is brainwashing his patients to distribute bacteriological warfare agents throughout various parts of the world.

Bond escapes from the clinic after Blofeld identifies him as the British agent. Bond arranges a raid on the clinic using men from Draco's organisation. The raid is a success, although Blofeld escapes. Bond marries Tracy, but she is murdered shortly afterwards by Irma Bunt, Blofeld's partner.
