Holder of Cruelty
In any city, in any country, seek out a person who once lived with you, but has since fallen out of contact. When you reach the house where the person now lives, knock three times on the door while calling for someone who calls himself "The Holder of Cruelty". If there is no answer, wait a week and try again. If a woman answers the door, politely apologize for the misunderstanding, then wait two weeks to try again.
Should, however, a man answer the door, you can ask him if he is who you seek. Should a sly smirk spread across his face, he will lead you to his living room and sit on the couch. He will light a pipe and ask if you want to hear a story. Agree. He will spin a vivid yarn of every act of sadism he himself comitted when he lived under your roof. Though the story is horrifying, concentrate only on it, and by all means do not look at any furniture besides the couch, or you will become part of it.
Eventually, the man will reach an especially gruesome part of the story, that tells of the unending torture of his own employee, a man he once loved. When he reaches the end of this section, he will ask if you want to see the employee. Agree, and he will lead you to a small room with little furninshing but a steel box. Wait for the man to unlock the box, then scream, "Cruelty shall be met with cruelty!"
If you acted correctly, then the vengeful spirit of the tortured man will arise. It will, with its unseen nose, tear the skin from the man's face. Its job finished, the spirit will blink twice before fading from existence. Open the box to find a stopwatch and the skeleton of a man. Take the bones and have them buried in any cemetery you can get yourself to, but keep the stopwatch.
That watch is Object 167 of 538. This is one step back from the point of no return. Enjoy it while it lasts.
