In the fall of 1789, on the western edge of the Yorkshire Dales, a dense, persistent fog enshrouds the village of Ingleton. Shadowed spirits hide in the mist and bedevil the townsfolk, heralding a tragedy that has befallen one of their own.

Edmond continues to search for Alexandra, his fiancée, who disappeared the same night that the mist set upon their town. Presumed dead by all others, he visits Alexandra's empty grave, desperate for any hint of what has become of her. Weary from the sleepless nights on his quest, no longer able to stay awake, Edmond falls into a dream before her headstone and there obtains clues from Alexandra as to her whereabouts.

Haunted all the while by a malevolent spirit, Edmond follows the trail that Alexandra left for him and enters the underworld, only to learn that he has been there before, and in fact, quite often. But more, he discovers how he is to blame for Alexandra's disappearance.

A dark literary novel rich in imagery, Discussion of a Decent Dream unearths the consequences of a child's decision to surrender his heart in exchange for unholy power and transcendent knowledge.
