Hitler's spies book?

Question

Im looking for a book for a relative. He said he read it a few years ago but cant remember what it was called. It was basically about one or more of hitlers spies whose spirits could leave their bodies and then they could enter the allied forces bases and find out their secrets and military strategies. Any body heard of this?
