Rebecka Martinsson has left her job at a prestigious law firm in Stockholm and moved into her grandmother's house in far Northern Sweden. She is still on the mend from the injuries she suffered in the last book in the series, The Blood Spilt. Rebecka is offered a position working as a prosecutor nearby and she decides to accept. Inspector Anne-Maria Mella and her partner, Sven-Erik Stalnacke, meanwhile, are investigating the brutal murder of Inna Wattrang, an executive at Kallis Mining. Rebecka's and Anne-Maria's paths cross frequently as the police try to uncover who wanted Inna dead. Rebecka assists them, burying herself in her work. Inna and her brother, Diddi, were friends with the head of Kallis Mining, Mauri Kallis for years. Their relationships became more complex over time, mixing business with friendship. Could someone close to Inna have been the one to harm her? The Black Path is the third book in the Rebecka Martinsson series. In the acknowledgements at the end of the mystery, Larsson says the series is half finished. Normally, authors aren't so upfront about how long a series will be. So, as a regular reader of the books, it's interesting to think about where the character of Rebecka will end up. Larsson immerses the reader in the Swedish setting and creates a cast of characters that are well-drawn. The book reminded me of Ruth Rendell.
