When the frantic, disheveled Edie Ledwell shows up at the office asking to speak with her, private investigator Robin Ellacott isn't quite sure what to make of the situation. Edie, co-creator of the popular cartoon "The Ink Black Heart," is being stalked by a mysterious online figure operating under the pseudonym Anomie. Desperate to uncover Anomie's true identity, Edie seeks Robin's help. However, Robin decides that the agency cannot assist and doesn't think much of it until a few days later when she reads the shocking news that Edie was attacked with a Taser and then murdered in Highgate Cemetery, the setting of "The Ink Black Heart." Robin and her business partner Cormoran Strike become embroiled in the search for Anomie's true identity. But with a complex web of online pseudonyms, business interests, and family conflicts to navigate, Strike and Robin find themselves in a case that tests their deductive skills to the limit and threatens them in new and terrifying ways. A gripping, devilishly clever puzzle, "The Ink Black Heart" is a true masterpiece.
