Trivia, insights & behind the scenes
Durbridge dominated British TV mystery for decades; this German adaptation preserves his signature 'domestic horror' approach where evil enters through the front door wearing slippers.
The 1966 German production kept Durbridge's original structure—three parts, each ending on a cliffhanger—because audiences literally wrote letters demanding answers between episodes.
