Daisy Wells and Hazel Wong both have a penchant for solving mysteries. In fact, outspoken Daisy is a self-described Sherlock Holmes, and she appoints wallflower Hazel as her own personal Watson when they form their own (secret!) detective agency. The only problem? There is nothing to investigate at the perfectly proper Deepdean School for Girls they both attend.

Or is there?

Follow Daisy and Hazel as they put their deductive skills and friendship to the test to solve a series of murders most unladylike involving a teacher's disappearing body, a poisoning at a high society tea party, a sinister slaying aboard the Orient Express, a brutal bully's demise at their school's Bonfire Night, and a holiday homicide in the stairwells of Cambridge.
