"A thrilling middle grade mystery series, perfect for fans of Robin Steven's Murder Most Unladylike. Set in eighteenth-century London, with all the fun and zest of Hamilton and inspired by real Black British historical figures. Twelve-year-olds Lizzie Sancho and Dido Belle are from different worlds--Lizzie lives in Westminster in her dad's tea shop, while Belle is an heiress being brought up by her aunt and uncle at grand Kenwood House--but they both share a love of solving mysteries. And when their eyes meet in the audience of the Drury Lane theatre one night, both girls are sure they've seen something suspicious on stage. Lizzie and Belle soon find themselves on the trail of a mystery--and becoming best friends. But can they work out what's going on in time to prevent a murder?"-- Publisher's website.
