On July 23, 1843, a terrible crime occurred in Canada, which still haunts psychologists and criminologists. Maid Grace Marks was accused of the extremely brutal murder of her master and his pregnant mistress-housekeeper. Grace was extraordinarily beautiful and very young - she was not yet 16 years old. The matter was complicated by the fact that she offered three different versions of the murder, while her accomplice offered only two. But he went to the gallows, and she had to spend her whole life in prison and an insane asylum - the lawyer managed to prove to the jury that she was feeble-minded. Grace Marks was released 29 years later. But was she truly mad? Booker Prize winner Margaret Atwood offers her version of the story of Canada's most famous criminal. But does she have the right?
