This is a new release of the original 1930 edition.

1930. The Master of the Day of Judgment is about a drug, created in Florence in the 16th century, that makes people see the Master (God). The downside is that they also see the Day of Judgment and all the demons of Hell, which leads them to believe that they are being attacked by the demons of Hell and then they commit suicide. The novel, set in Vienna in 1909, is structured like a murder mystery, with the identity of the victim only being revealed near the end. A Kirkus review said, The identity of the Master provides a solution that, like that of Dr. Jekyll and Mr. Hyde, is more disturbing than the mystery itself.

In the Viennese autumn of 1909, famed actor Eugen Bischoff is driven to suicide. All eyes are on Baron von Yosch, who was once the lover of the dead man's wife. The Baron has nothing to hide. But why was his pipe found at the scene of death? Could you prove your innocence, with your memory of events so confused? Then there was the girl on the phone who distinctly referred to 'the Day of Judgment' - the actor's dying words... And there were other deaths that autumn, and it became harder to track down the invisible enemy - a monster who fed off intrigue, imagination and fear. The very things that drive us. The very things we cannot control.
