On a similar note, I hate books where everything (murder is discovered, plucky journalist suspects foul play, runs around digging up a 20 years old cold case, bad guy chases her, etc) happens in a day or two. If you throw in heroes solving puzzles that have baffled experts for years in that day, I will throw the book at the wall.
To me, that doesn't create a sense of urgency. Instead, it leaves me wondering why, if it was so obvious and so many people were trying to find the Mcguffin, why did no one find it before? Or, how can they fit in an interrogation, a car chase, an online search for obscure information and some nookie before breakfast.
