A man and his dog find a child’s skeleton in an abandoned mine, and a white woman, Sylvia Stewart, is attacked in Victoria park on her way home from work. A West Indian, Donald Palmer, is arrested who denies the assault but he knows the victim well. Under questioning in front of her parents she denies knowing a black man and Dawson believes the prejudice of the time prevents her telling the truth. DI Burns sends Dawson to the library to look at newspaper back issues for news items about a missing six year old boy.
