One of eight quartets from G. W. Thomas' The Book of the Black Sun, a collection of Cthulhu Mythos horror fiction. Each quartet is made up of a micro fiction piece of 100 words or less, a flash story 300-500 words, a short story of around 2000 and a longer one of 3000-5000 words. This one features "They Never Knew", "If You Want To Leave a Message", "The Faces" and "At the Sound of the Tone...". James Ambuehl wrote: "This collection of exclusively Mythos stories is a very inspired one, many of the stories exhibiting a craft and ease of style usually somewhat lacking in the work of others."
