If you know Montmartre, the French Impressionist movement or anything to do with Salpetriere, then this book should be of interest to you. "Mesmerised" by Michelle Shine, might not be as glitzy as some scenes out of Moulin Rouge but the story of Gachet and his patients is genuinely interesting. Like today, there are those who believe in homeopathy and those who don't. Fascinating stuff!
