City of Dark Hearts, by William Horwood and Helen Rappaport writing as James Conan (Arrow Books)
This book is a real page turner. It is set in Chicago in 1893 where a young girl, Anna Zemeckis, goes missing. Emily Strauss, a feisty girl reporter (called 'stunt girls' in those days) sees the potential in the story and persuades the famous Joseph Pulitzer of New York World to commission her to investigate. Immediately, against the glamorous backdrop of the World's Fair, she is plunged into a sinister underworld of violence, pornography and prostitution. Extensive research by the co-authors ensures realistic atmosphere and chilling detail which grip the reader's attention right through to the story's compelling climax.
