The chameleon's shadow / Minette Walters

When Lieutenant Charles Acland is flown home from Iraq with serious head injuries, he faces not only permanent disfigurement but also an apparent change to his previously outgoing personality. Crippled by migraines, and suspicious of his psychiatrist, he begins to display sporadic bouts of aggression, particularly against women, especially his ex-fiancee who seems unable to accept that the relationship is over. After his injuries prevent his return to the army, he cuts all ties with his former life and moves to London. Alone and unmonitored, he sinks into a private world of guilt and paranoid distrust... until a customer annoys him in a Bermondsey pub... Out of control and only prevented from killing the man by the intervention of a 250-pound female weightlifter called Jackson, he attracts the attention of police who are investigating three ‘gay’ murders in the Bermondsey area which appear to have been motivated by extreme rage... Under suspicion, Acland is forced to confront the real issues behind his isolation. How much control does he have over the dark side of his personality? Do his migraines contribute to his rages? Has he always been the duplicitous chameleon that his ex-fiancee claims? And why – if he hates women – does he look to a woman for help?
