In 2009 the G4S cash service depot in Stockholm was raided using a helicopter to land on the roof, and millions of kroner was taken but no one knows how much. The cash was never seen again. Airforce fighters tried to get down the helicopter and the police were aware they had weapons. The robbery was known about and it was planned very well by the robbers in every detail, they had worked out what they were going to do. This is a true story based on a real life heist which centres on the life of four men and you get to know their characters, it certainly is a book filled with twists turns suspence and the ending is as good as the whole book and worth waiting for would definitely recommend this
