After reading Richard Powers’s Capgras Syndrome novel The Echo Maker, I figured I should read Rivka Galchen’s take on the same disorder. The main character is hilarious (he believes his wife has been replaced by an imposter and frequently refers to her as “the simulcrum”):
Sleep did not visit me, but stray strands of of the simulacrum's hair gave me the continual illusion of fleas mutely festivaling on my body.
The book is written in first person, from the perspective of the person with Capgras, and it’s a particularly effective technique for the story. We know that his wife hasn’t been replaced, but we experience the rationalizations and logical contortions required for the main character to believe his delusion. If the book were longer, or if Galchen wasn’t such a good writer, it might have gotten tiresome, but I found it to be a very entertaining and refreshing read.
Probably a good book to read in advance of Gravity’s Rainbow…
