Synopsis for "The Pact"
Journey into Mystery #2
Henry Conrad was writing a book on witchcraft; he wrote about how his ancestor Branders Conrad was accused of practicing witchcraft in the very same house. Henry was asked by the publishers, Morrison and Linster to write a book about witchcraft and wanted to find evidence that people believed that his ancestor was a witch. Hours later, a man calling himself the "Uninvited Guest" approached him and claimed that he was Satan himself. Henry, believing that that the man was joking, told the guest about his ancestor who was accused of witchcraft. The Uninvited Guest took Henry to June 15, 1693, where the Uninvited Guest's past self, who was, in fact, Satan, was making an agreement with Branders Conrad, granting him the ability to see the future. After Branders had learned that he would have a table full of gold and a very beautiful woman as a wife, he began to regret his agreement. The Uninvited Guest told Henry that people were hungry for power and they did not think before summoning him. The next morning, Henry woke up and saw that he had finished writing about his ancestor on the typewriter, then he went outside and saw the print of a hoof next to each shoe mark.

Synopsis for "Beware!! The Ghosts Surround Me!!"
Two robbers flee a crime scene and head towards the woods. One falls, breaking his leg, and the other ruthlessly shoots him as his identity may be found out by the police. Stopping at an abandoned house, the man sees two ghosts, but finds out they are creatures from another dimension, who can't touch him. The man laughs at the situation, imagining other people who have run from the house, believing it to be haunted.
