There is no rule on how to write. Sometimes it comes easily and perfectly; sometimes it’s like drilling rock and then blasting it out with charges.”

Ernest Hemingway’s description of the creative process sounds a bit like fracking to me – occasionally you strike oil and out comes the black gold in an effortless stream, but more often than not you’re drilling into rock, setting your charges and then blasting away. The British Government called a halt to some experimental fracking in the north-west of the country because it seemed to be causing minor earthquakes. The compensation of a good day’s writing, even if it involves some difficult detonations, is that the effects of it can sometimes feel seismic. It’s one of the few things that really does make the earth move.
