It's Murder At The Box Office

It's 1929 and a young Irish woman working in the box office of a London cinema is in trouble and goes to Scotland Yard for help. There she meets the tweed-suited, pipe-smoking Inspector Flora French who urges Molly to reveal all she knows, but before they can meet again, the girl goes missing. With little to go on, the inspector is desperate to save her, and her own reputation. Inspector French's inquiries eventually reveal other related incidents and the further she delves into the affair, the more intriguing it becomes, revealing a tangled web of murder and crime in this deliciously complex tale. This cracker of a story is for readers who love historic fiction and yearn for a time when life was simpler, when there was little technology, and detectives and criminals lived by their wits.
It's Murder At The Box Office is a feminised book, which normalises female agency and participation in the narrative. The original text, typical of its time, had female characters who were minor, passive or non-existent.
