In Tokyo, Charlie Hillier discovers you can't always bank on the truth.

Fresh off a harrowing experience in Russia, Charlie is keen to lay low, and his latest posting to Tokyo offers him the chance to immerse himself in a truly foreign culture.

Charlie is soon drawn into his first consular case when a successful young investment banker winds up in a coma following a car accident. After a man claiming to be a friend of the banker's turns up dead, Charlie and the Tokyo Metropolitan Police inspector assigned to investigate the murder, Chikako Kobayashi, discover that trusting the banker - who emerges from his coma with amnesia - may be a dangerous decision.

As Charlie tries to sift truth from deceit, he's unsure if he's dealing with a man whose accident has brought about a profound change for the better or a devious criminal lurking behind a convenient facade.
