LEOPARD

Josef Tanaka, Japanese-American medical examiner, returns to Japan for his brother's funeral and learns he was savagely murdered. With the misguided help of his friend, American detective Bill Fogarty, he plunges into the twilight of Tokyo's underworld, home to a programme of murder. And as Josef and Fogarty draw closer to his identity, the Leopard is watching, waiting - for the perfect moment to destroy . . .

MIND KILL

Meanwhile, Bill Fogarty is being haunted by terrifying visions - whatever has tapped into his mind has redefined fear . . . Someone knows how Maria was killed and what is happening to Bill . . . Someone who is taking revenge with the most lethal and untraceable weapon in the world. His mind.
