Misery and Other Lines by C. C. Adams
"Welcome to Halloween in the capital.
No matter where you need to get to, whether you're going out, going somewhere, or going home, London Underground is at your disposal. Teeming with passengers, just like you; many of them masked, made up or in costume to celebrate the Hallowed Eve.
But some of them are different; sly and sinister. Wearing masks of humanity. Or, sometimes, no mask at all.
Keep your wits about you, watch your step, and maybe you'll survive the night.
"Adams knows how to make your skin crawl... He can change a scene from normality and mundanity of life to open-mouthed terror in seconds." - David Watkins, author of The Exeter Incident
