Schneier on Security

I recall reading, a couple of years ago, an interview with a legitimate safecracker in some men's magazine. The guy had started out working part-time for a locksmith, and now (probably at about age fifty) makes a good living opening safes for the owners and their insurance companies.

What stuck with me from the article was mention of a small book that the locksmith had given him, and that had set him on his career path. He described it as a straight-forward guide to safecracking for locksmiths, titled "The Art of Manipulation." What references I've dug up indicate that it's a 1950's or 1960's-era publication, long since out of print.
