The Third Seal Andrew Woodcock

DI Marshall is a police officer with a difference - she is ambitious, she is a woman, and she is black. In the most difficult and personally dangerous case of her career, she finds herself up against a serial killer on the loose in South London and Soho, and also against a jealous and prejudiced senior colleague. The story builds to a shattering climax - and one of the most unexpected twists in the tail of any modern thriller.
