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.
