The Flames: A Fantasy

The story takes the form of a long letter written by one old university friend to another. The recipient of the letter, known only as "Thos" (a college nickname, short for "Doubting Thomas") introduces the strange document, from a friend known only as "Cass" (another nickname; short for "Cassandra", an allusion to the friend's apparently prophetic abilities). Cass is regarded as a harmless eccentric by his friends, but Thos notes that his prophecies and preoccupations, wild as they may seem, have a habit of coming true. Thos also notes, ominously, that Cass's letter "bears the address of a well-known mental home".

Cass's letter, which forms the bulk of the novel, describes his contact with a bizarre form of alien species. Whilst holidaying in the Lake District, Cass is inexplicably drawn to a lump of rock, which he pockets and takes back with him to his room. There, he is driven to place the rock on the fire, and this action releases a bizarre form of alien life - a living flame, which has been trapped in the rock for millennia.

The flame reveals itself to be one of an ancient alien race who originated in the photosphere of the Sun. Solar catastrophe has distributed the ancient race throughout the planets of the Solar System, and the flame-beings can only be woken by intense heat. The flame and Cass discourse at great length about typically "Stapledonian" topics - the life of the spirit, the role of the individual and the purpose and meaning of the universe. Over the succeeding nights they develop a strange friendship, in which Cass reactivates the flame in his hearth, (which slumbers in the cold rock of the firebrick) with a hot coal fire.

Eventually, the flame reveals that it has grand plans for Cass - it wishes him to be an ambassador for his people, and explains that the flame and his race have been manipulating events on Earth in order to better their chances of survival, manipulation that included the unfortunate suicide of Cass's wife. The flame proposes that Cass aid in introducing the flames to humankind. In exchange for a permanent home on earth - a zone of extreme heat - the flames will use their telepathic powers to assist mankind. Cass agonises over this offer for two days, and comes to the decision that humanity must stand or fall on its own merits, without outside help or control. He reactivates the flame and douses it violently with cold water. The rapid change in temperature kills the ancient being at once.

Cass, torn with regret and doubt, but set in his course of action, begins finding and killing the little flame creatures wherever he can find them. Posing as a journalist, he visits a foundry where locomotives are made and attempts to shut off the furnace. He is arrested and placed in a mental home.

Thos takes up the final part of the narrative, visiting Cass in the asylum. Cass claims to have been in contact with the flames once more, who have re-established contact with their brethren on the Sun. Cass tells the story of their race: how they became part of a "cosmical mind" reaching out to the creator of all things, and how this enterprise failed. Thos hears nothing from Cass for a few months, but is later informed of Cass's death - he perished in a fire at the asylum, which he started himself.
