seeing something nasty in the woodshed

I am reading Da Vinci Code for a project, and I'm underwhelmed. On first glance, it read like a Sidney Sheldon - but I'd much prefer to be reading a Sidney Sheldon. The one delightful moment so far has been that Sophie goes into the woodshed at her grandfather's country house and sees something nasty.
I hadn't suspected that Dan Brown had a sense of humor, but surely that can't be coincidence?
