This central street of Cordoba, known as the goblin of Almonas street, where it is told by Teodomiro Ramírez de Arellano, is the story of a young girl who received a rich inheritance from her parents that provokes the envy of her brother who is envious of the favor towards her, plans to assassinate her.
The story tells how the woman who lives in a house on Almonas Street, today Gutiérrez de los Ríos, meets a goblin, who is nothing more than a man, named Martin, condemned to wander eternally for having mistreated his elderly father. He is secretly in love with her, but because he is ugly and very short, she does not belong to him. Martin knows the murderous plans of the brother and warns her, but she does not believe him and decides to move from home to the Jewish quarter.
On Christmas Eve, returning from the mass of the cock in the Cathedral, the brother waits for the girl and murders her with a knife in the heart, staying with her with his money and finally moving to the house on Almonas street. He never believed the story that the elf told him, but he hangs him one night. The neighbors after hearing the cries, appear and find the body of the hung brother and Martín el Duende and this indicates that it had been Divine providence. After this he disappeared from the face of the earth.
Since then numerous are the appearances of a bitter girl for having distrusted who warned, the murderer executed and hanged and finally the goblin man who did justice to everyone.
