I have recently read Nicholas Stuart Gray's Mainly in Moonlight (1965) for the first time.
Mainly in Moonlight consists of ten short tales of sorcery and the supernatural, the third of which gives its name to the book. One story is an addition to Over the Hills to Fabylon, another to Grimbold's Other World and, as mentioned in the 100th anniversary article, yet another story, one that is told by a demon with a sense of humour, may have given some ideas to Jonathan Stroud.
There is not much quotable material in the book, but some of the stories inspire a small amount of commentary.
The story titled Mainly in Moonlight has something to say about the inappropriate use of magic and people who get themselves out of a tight corner only to fall into a worse one.
A young man called Colin decides to seek out a sorcerer to request a magic charm that will get him something he has set his heart on. The sorcerer says that before his wish for a magic spell can be granted, Colin must serve him for one year.
Colin has to perform tasks such as drawing water, lighting fires, baking bread and tending to an invisible horse. He thinks constantly of escape.
A creature living at the bottom of the well offers him a way out, but the catch is that he must serve it for one year. Life down below turns out to be worse than it was with the sorcerer.
Again and again Colin is rescued from a disheartening situation only to be expected to serve his new master for one year.
“There is only one simple truth about magic. You get a lot that you didn't ask for and absolutely nothing that you wanted!”
This is certainly true in many cases. However, the sorcerer keeps his word and there is a good outcome for Colin.
