Being a secret agent can be tough at times. All those private jet rides, sipping poolside Martinis and generally enjoying all the delights the world has to offer must be really taxing. If this sort of painful lifestyle interests you, you could go through years of intense training. Or, you could read "How to Archer" by fictional ISIS agent Sterling Archer.
Archer, of course, is the somewhat adult cartoon comedy from US cable channel FX, which recently aired the first episode of its fifth season. I suppose the creators must have seen an opportunity to cash in on the show's popularity by putting together a book about being a super spy (well, an Archer-like spy), in the same style as the Zombie Survival Guide from Max Brooks.
Though the usefulness of the advice offered in the former is debatable — the section on "Stellar Navigation" is particularly insightful.
You can read a small part of the book on the HarperCollins website, or you can grab it for a little less than $18 from the Book Depository.
