London fog never lies, it just masks. While other detectives are searching for the murderer, Alice Leidy, a 21-year-old female detective with a vicious tongue, is dissecting the lies behind the truth.
A perfectly dismembered corpse in a secret room, with a withered rose clenched in the hand, is the beginning of all mysteries. As the daughter of a famous detective, Alice is forced to take over the shabby office left behind by her father's disappearance, as well as a series of unsolved cases that even Scotland Yard is helpless to solve.
But when she gets closer to the truth, she finds that every clue points to the doubt she least wants to face - her father's mysterious disappearance three years ago was not an accident, but a dead move in this huge chess game.
