History meets mystery in this fantastic new series! Debut author Jordan Stratford imagines an alternate 1826, where Ada Lovelace (the world's first computer programmer) and Mary Shelley (author of Frankenstein) meet as girls and form a secret detective agency! When Mary Godwin and Lady Ada Byron first meet, they don't exactly hit it off. But with crime on the rise, the unlikely pair form a detective agency to hunt down clever criminals on the streets of London. Their first case involves a stolen necklace, a false confession, and lots of suspicious suspects - but these are no match for Ada and Mary. Filled with daring balloon chases, vile villains and two unforgettable heroines, The Case of the Missing Moonstone is the first in a thrilling new series; perfect for all aspiring sleuths.
