This is a picturesque tale of the consequences of wealth attained by the aid of the supernatural which hangs about the ancient village of Endenich, near Bonn, where at the end of the seventeenth century there dwelt a certain sheriff and his son, Konrad, who was a locksmith by trade. They were poor and had lost everything in the recent wars, which had also ruined Heribert, another sheriff, who with his daughter, the beautiful Gretchen, eked out a frugal but peaceful existence in the same neighbourhood. The two young people fell in love with each other, but Gretchen's father, becoming suddenly and mysteriously very rich and arrogant withal, desired a wealthy or highly placed official as his son-in-law and not a poor lad with no expectations such as Konrad, the locksmith. The lovers were therefore compelled to meet in secret, and it was on one of these occasions that Heribert, surprising them together, attacked Konrad and felled him to the ground in his rage that he should dare to approach his daughter. Spurred by his love and knowing that he could never hope to win Gretchen without wealth, the unhappy youth decided to barter for gold the only possession left to him--his soul. Now there lived in the churchyard a Lapp wizard who made such bargains; so in the dead of night Konrad took his way to this dreadful and unfrequented spot and exhorted the sorcerer to come forth. At the third cry a terrible apparition appeared and demanded to know his wishes, to which the terrified Konrad could only reply: "Gold." Thereupon the sorcerer led the way deep into a forest and, pointing mysteriously to a certain spot, disappeared. At this spot Konrad found a chest full of gold and silver coins, and returning to Bonn, he bought a house the splendour of which surpassed that of Heribert, who could no longer refuse his daughter to so wealthy a suitor. The young wife tried all her arts to solve the mystery of her husband's wealth, and he was at length about to reveal it to her when he was suddenly arrested and thrown into prison. Here he was put to torture by the authorities, who suspected him of robbery, and at length he confessed that he had found a treasure, while to his wife he confided the gruesome details, all of which were overheard by his jailers. He was released, but almost immediately re-arrested on the suspicion that he had killed a Jew named Abraham, who had amassed great sums during the wars as a spy. Tortured again, in his extremity he confessed to the murder and named Heribert as his accomplice, whereupon both men were sentenced to be hanged. Just as this doom was about to be carried out a Jew who had arrived from a far country hurriedly forced his way through the crowd. It was Abraham, who had returned in time to save the innocent. But his sin did not pass unpunished, for Konrad died childless; he bequeathed his wealth to the Church and charities, in expiation of his sin of having attained wealth by the aid of an evil spirit.
