The Fire Witness by Lars Kepler was first published in 2011 and has been published again in November 2018 by Vintage Crime/Black Lizard. Lars Kepler in the pseudonym used by married couple Alexander Ahndoril and Alexandra Coelho Ahndoril. This is #3 in their Joona Linna series and it can easily stand alone if you have not read the previous books. However, this series is so intense that readers will enjoy reading everything by Lars Kepler. Joona Linna is a troubled detective in Sweden. He is called upon to observe the investigation of a double murder which takes place at a home for troubled teenage girls. A resident and a caretaker have been killed and a missing girl is believed to have committed the crimes. The detective is approached by a medium who claims to have been visited by the ghost of the murdered girl and Linna is intrigued by this. The story develops quickly but nothing is as it seems. This suspenful read will appeal to readers who enjoy murder mysteries with a twist. Thank you to Knopf Doubleday Publishing Group and NetGalley for the e-ARC in exchange for an honest review.
