Used book – The Constant Gardener, John Le Carré, Mimi Perrin, Isabelle Perrin

Tessa Quayle, a young and beautiful English lawyer, has been brutally murdered in northern Kenya. Her companion and alleged lover, an African doctor from a humanitarian organization, has disappeared. Justin, Tessa's husband, a career diplomat at the British High Commission in Nairobi and an amateur gardener, embarks on a solitary quest in search of the killers and their motive.

His quest takes him to London, then across Europe and to Canada, only to bring him back to Africa as far as South Sudan, and finally to the very scene of the crime. An odyssey full of violence and fury where the dark machinations of pharmaceutical multinationals are plotted, and strange political alliances are formed.
