1834. Sophia Thompson wants nothing more than to be one of the famed Bow Street Runners, London's most elite corps of detectives. No woman has never before joined their ranks-- and her family has forbidden her from pursuing such an unladylike goal. When her cousin Daphne begs Sophia to look into the suspicious death of Daphne's brother, she has a chance to prove her capabilities. But the murderer may be even closer to her family than she ever suspected. -- adapted from jacket.
