Matthew. Today's (13) puzzle. Books normally have 1st two page spread being pages 2 and 3. The last in this book would be 752,753. This means there would not be a middle two page spread, there would be two...?
Did you assume 1st 2 page spread is pages 1 and 2?

@Neal: Yes, the book starts with page 1 on the left hand side (ie the inside cover), and ends with page 754 on the right (ie the inside back cover).
