A mathematical mystery that crosses many centuries—from the ancients to turn of the century Paris to present day Europe. If you like math or find it's history intriguing this book has it all. If you like art too, then this is the perfect book. While the title hints at the mathematical and murderous themes it leaves out how much art and art history is also included. Spending time with Picasso and the beginning of Cubism, having drinks with Toulouse-Lautrec. It's an intellectual read, continuously interesting.
