"It's 1876, and Charles Lenox, once London's leading private investigator, has just given up his seat in Parliament after six years, primed to return to his first love, detection. With high hopes he and three colleagues start a new detective agency, the first of its kind. But as the months pass, and he is the only detective who cannot find work, Lenox begins to question whether he can still play the game as he once did. Then comes a chance to redeem himself, though at a terrible price: a friend, a member of Scotland Yard, is shot near Regent's Park"-- Provided by publisher.
