The Nameless, a loose-knit group of vigilantes who fight the evil forces of the occult, have come in the posession of an old painting by Bohemian warlock Pavel Dvorak who was burned at the stake for witchcraft in 1476. They, through a series of intermediaries, trying to remain anonymous, ask Mr. Simons to verify the authenticity of the painting. Sir O’Reilly and Mr. Mason, each through different channels and for different reasons, come to the aid to Mr. Simons’ attempt.
Quickly, it turns out the painting has a very storied past and that a person is locked inside of it, only becoming visible at roughly 10pm each evening, showing more and more of himself. It turns out to be late Mr. Armitage, a erstwhile companion of Sir O’Reilly who died when banishing a malevolent spirit from a farmhouse in a village outside of Arkham.
Doing their research, the investigators find a way to ressurrect Mr. Armitage, which was The Nameless’ reason for giving them the painting all along. They manage to perform the ritual and ressurrect Mr. Armitage, only for him to disappear without a trace the following day.
