German radioplay series, conceived by Erik Albrodt. The series debuted in 2008 on the Dreamland Productions (3) label. Two more episodes were announced, but production soon came to a halt. As a result, the series moved to Albrodt's own label, Earliner, in 2011, with the two previously announced episodes being finally released in 2012 in digital format only. The series was subsequently discontinued.

In 2016, the concept was revived by Sebastian B. Pobot for his label Maritim. Instead of continuing the series, previous episodes were discarded in favor of newly written material, resulting in a standalone reboot. Information about this series can be found at Twilight Mysteries (2).
