Equoid is a short story in Charles Stross's Laundry series, an fun horror-espionage series that seethes with the horrors of Otherworldy evils threatening humanity's existence and British bureaucratic process in equal quantities. This story revolves around suspicious deaths in very,very rural England and the true nature of Unicorns...they're not happy, bouncy things you'd want your daughter playing with, not by a long shot. The plotline does get muddy at a couple points insofar as who is doing what and why, but overall Stross does and excellent job of weaving a tale filled with mystery, horror, and no little bit of humor that culminates in a disturbing, action-filled ending. I give extra kudos for the innovative Lovecraftian tie-in and the Cold Comfort Farm (one of my favorite movies) references. The story is a good stand-alone if you've never read anything in the Laundry series before, otherwise I recommend picking up the first book in the series The Atrocity Archives. Three out of five stars.
