From its start in 1937, as the Japanese overrun the Chinese port of Nanking and massacre hundreds of thousands, to its narrative core in 1990, as a disturbed young British woman who calls herself Grey searches for the hidden truths that made her the mentally fragile person she is, Hayder's third book (after 2002's The Treatment) is a thriller of rare art and gripping excitement. Hayder, one of the rising stars of British crime fiction, teaches at a university in Bath and has worked as a hostess in a Tokyo nightclub. Both experiences add to her book's unusually rich atmosphere. Grey, who lives on the fringes of the academic world, tries to find out in Tokyo whether a piece of 16mm film taken during the Nanking atrocities actually exists—and whether it will ease her pain. When an elderly Chinese professor, a survivor of Nanking, at first refuses to help her, she drifts into a well-paying job as a night club hostess. Eventually, the story becomes a beautifully paced, three-way duel among an aged Japanese gangster who wants to live forever; the Chinese professor, with secrets too horrible to hide any longer; and Grey, a courageous young woman unlike any other heroine you're likely to find in a thriller.
