Impossible Virgin — Peter O'Donnell

Modesty Blaise's friend Novak died trying to preserve his discovery of the Impossible Virgin, a secret that meant enormous wealth. But right at the last moment, he babbled. When Modesty makes a forced landing in Central Africa, she meets the man who possesses Novikov's secret without knowing it -- Giles Pennyfeather, the guileless and blundering young doctor with a gift for healing. In saving Giles from Brunel, a dangerous killer, she buys yet another ticket to danger, for Brunel is determined to have the secret. Modesty and her lieutenant, Willie Garvin, take on Brunel and his partners in a fierce and devious battle, where Modesty is brought to the most shattering reverse she has ever suffered. How she fights back, and at last learns the truth of the Impossible Virgin and her ferocious guardians, brings this fifth tale in the saga of Modesty Blaise to an astonishing climax.
