A beautiful lady asked the porter in our story to carry her things home. The porter agreed and he was invited to stay for the night but on one condition – he was not supposed to speak of that which did not concern him. It was then things took a strange turn. Three Persian Calenders came as well. Later on, the vizir joined the group. One of the ladies began singing, the other one fainted. Some slaves were brought inside, and they had to kill the guests. Do you think the porter managed to keep his promise?
