I'm looking for the short story probably entitled "The Cinder Children" from a collection of horror fiction that may have contained some Richard Matheson stories or been a tribute to Matheson. I read a copy of the collection around 2002 and promptly lost the book as I moved out of state.
The story featured a guest in a house who is admonished to shut his room's fireplace flue before he goes to bed. The house is haunted by children who were burnt to death in the fireplace, and he fails to heed the warning and is damned to live in a sooty cinder hell.
Anyone else remember this one? Thanks in advance.
