Hayley Burke has landed a dream job as the curator of Lady Georgiana Fowling's First Edition library, in Bath. The only downside is working alongside the finicky Glynis Woolgar, Lady Fowling's former secretary who does not like Hayley's ideas to modernise the library's Society. When one of her plans to breathe new life into the Society takes flight - an Agatha Christie fanfiction writers group - Hayley is thrilled. But when one of the group is found dead in the venerable stacks of the library, Hayley has to catch the killer to save the Society and her new job.
