Author Dirk Trost was born in Duisburg in 1957. Even as a young boy he spent his summer holidays in East Frisia, browsing the adventure stories of Enid Blyton, Erich Kaestner and – on long winter evenings – the “forbidden” mystery books of his grandfather, who thought they were securely hidden in the back of the closet. What could be a more logical result than writing his own adventure story – or, even better, his own whodunit? It took 50 years until this childhood dream came true with the story of the former defense attorney Jan de Fries.
