So is there a book out there about the Secrets of the Secret Service?

I don't know. There was a very good hour-long special on Discovery Channel (or one of the similar educational channels) about the Secret Service. But I've never heard of a book about them.

You've probably found these already, but below are a handful of Secret Service books available from Amazon.com. The third book, Standing Next To History, appears to be the best, judging by the customer reviews (it was written by one of Reagan's agents).

The Secret Service--The Secret History of An Enigmatic Agency

Secret Service by Mark Beyer

Standing Next To History--An Agent's Life Inside The Secret Service

Protecting The President

Good night!
