The Yellow Sign (Unabridged‪)‬

From The King in Yellow: Anyone who possesses, even by accident, a copy of the sign is susceptible to some form of insidious mind control, or possession, by the King in Yellow or one of his heirs. The stories also suggest that the original creator of the sign was not human and possibly came from a strange alternate dimension that contains an ominous and ancient city known as Carcosa. The finder of the sign gives it as a gift to her future lover with disasterous results!
