A German radio adaptation of The Fall of the House of Usher. All four actors, Oliver Feld, Tobias Kluckert, Claudia Urbschat-Mingues and Kaspar Eichel all give top-notch performances and the drama is genuinely chilling, with the climax being simultaneously Nightmare Fuel and a Tear Jerker, particularly thanks to Feld's performance as the protagonist Philipp.

And one by one dropped the revellers in the blood-bedewed halls of their revel, and died each in the despairing posture of his fall.
