Protecting the garden from pest

I "borrowed" a book from my sister in law on solving gardening problems. She just may never get this book back. Anyway, it has all kinds of information on protecting your plants from deer, raccoons, rabbits and gophers. Something has been stealing our peppers. I’m thinking it’s a pest of the two legged kind and there is nothing in the book that tells me what to do for that.
Since everything is in containers I moved them closer to the house for now.
