Amy suspects her boss is a killer. He says she's lost the plot. As he tries to discredit her, Amy fears for her job, her sanity and her life. But she's a tough professional, not a quitter and somehow she'll find a way to fight back...
The book is almost unique, being a psychological thriller set in the dog-eat-dog environment of London's financial district. When She Was Bad by Tammy Cohen is a psych thriller set in an office and therefore somewhat similar.
