In Ian Fleming's tenth James Bond novel, 007 pursues Ernst Stavro Blofeld, the head of SPECTRE, on a deeply personal mission. His trail leads to Piz Gloria, an alpine allergy clinic in Switzerland where Blofeld, hidden under a new identity, is brainwashing young women to spread a biological agent that would devastate Britain's agriculture. Disguised as genealogist Sir Hilary Bray, Bond infiltrates the fortress-like facility, but his cover is blown, triggering a deadly ski chase and avalanche. Amid the danger, Bond falls in love with Teresa "Tracy" di Vicenzo and marries her—only for tragedy to strike moments after the wedding.
