What a classically creepy book! Reminiscent of the film, _The Bad Seed_, this story of twins, Niles and Holland, absolutely enraptured me. Despite being written in 1971, it felt modern and had such an ominous atmosphere! It wasn't terribly unpredictable, but more in the way that foreshadowing hints at events than the plot being worn or tired. And, obviously, the twins aspect was a nice twist on the "Bad Seed"-esque plot. My only real complaint came from the edition that I read - it was a first edition that had not been well cared for - it was very musty and just smelled terrible! Though I suppose that the olfactory horror rather added to the horror found within the pages themselves. I am very curious to see the film version. Honestly, I am surprised that this book isn't better known - the atmosphere, plot and characters all stand out so much from the modern psychological thrillers.
