For the first time in her career, investigative reporter Annika Bengtzon is covering the glamorous Nobel Prize Dinner, traditionally held in Stockholm's City Hall. Some of the most notable scholars in the world are enjoying themselves on the dance floor, the wine is flowing, when gunshots suddenly break out. Bodies fall to the floor and Annika is pushed down by someone fleeing the scene. She only catches a glimpse of the suspect, but soon she is caught in the middle of an intricate drama with links to international terrorism, global pharmaceutical corporations, and Alfred Nobel himself. Only this time, she's not just a reporter, she's a key witness to multiple murders. Bengtzon has no choice but to track down The Kitten, a professional American assassin who may know something about the Nobel killings.
