Tokyo
Mo Hayder
 The story is about a young woman (nicknamed 'Grey' by a fellow mental hospital patient) who is obsessed with the 1937 Japanese invasion of Nanking, also known as the Rape of Nanking. She travels to Japan in order to find a professor said to have rare footage of the massacre detailing an event that she could not otherwise prove occurred. The professor decides that he will only show her the tape if she was to procure an unknown ingredient of Chinese medicine from the local Yakuza group. After being recruited into a host club, Grey finds her chance.
