Additional German volumes In German, the Barney mysteries are known as the "Rätsel um...-Serie", or "Riddle of... series". In addition to translations of the six English titles, there are two additional volumes: Rätsel um den tiefen Keller ("Riddle of the Deep Cellar"). This is a translation of the one-off book, The Mystery That Never Was Rätsel um die Falschmünzer ("Riddle of the Counterfeiters"). This "translation" was in fact an original work by the series' German translator Brigitte Blobel, published by C. Bertelsmann Verlag in 1977 []. It had not been authorised by Darrell Waters Limited, and so was soon taken out of print.
