Arne Dahl is the alter ego of Jan Arnald, who was born in 1963 and obtained a PhD in literature in Stockholm. He has achieved global success with his Intercrime series of crime fiction novels and his thriller series featuring the Opcop quartet. He has won several international awards and his books have sold more than 2 million copies in Germany alone. In 2016, Arne Dahl started a new series featuring the investigative duo Berger & Blom with the publication of “Watching You”, which once again garnered him enthusiastic praise. The two follow-ups each spent more than half a year in the top 10 on the Der Spiegel best-seller list in Germany.
