Utilizing every stealth technique you learned from the army, or rather every stealth technique you learned from deserting the army, you surreptitiously creep over to the bookshelf.

As you gaze upon the countless moldy titles filling your deceased uncle's bookshelves, you realize you're in over your head. You couldn't get a clear glimpse of what book the hunchback pulled in order to reveal the secret passage, but you're sure it was somewhere on this shelf.

After ruminating on what you saw, you are able to narrow your choices down to, let's say, four potential book titles. It probably wouldn't hurt to try all of them, but you've only got two hands, and one of them is covering your mouth so as not to alert the hunchback with a sudden sneeze.

You'll try pulling on:

• History of the Mexican-Canadian War.
  
  
• Memoirs of a Gong Farmer.
  
  
• The Far Side Gallery.
  
  
• Chicken Soup for the Anarchist Soul.
