The grand magus of horror unfolds a catalogue of gruesome and ghoulish delights in the three novellas which comprise Unholy Trinity. In Sanguinarius, we encounter the beautiful virgin bride of Count Ferencz Nadasdy and her horrific initiation into the satanic rites of a hideous passion. Sadonicus relates the tale of the mysterious Mr S and the unholy vengeance visited on his face and fortunes. And Sagittarius invokes the sadistic pleasure of an actor whose plays of torture and death become terrifyingly real.
