The Man with the Red Tattoo by Raymond Benson
When a British businessman and his family are killed in Japan, James Bond suspects a mass assassination. Investigating with the help of beautiful Japanese agent Reiko Tamura and his old friend Tiger Tanaka, Bond discovers that two powerful factions controlled by the mysterious terrorist Goro Yoshida are playing God. Between them they have created the perfect weapon, one small and seemingly insignificant enough to strike anywhere, unnoticed. With an emergency G7 summit meeting just days away, it's a race against time as Bond confronts both man and nature in a desperate bid to stop the release of a deadly virus that could destroy the Western world.
