Old Mission Street Coca-Cola Bottling Plant once unwittingly employed Nazi spy

If you've lived or worked in San Francisco for any length of time, you have probably seen the towered building, located at 1500 Mission Street, near Eleventh., and once home to the Coca-Cola Bottling Company. Its tall clock tower used to bear the company name. It's one of those sites where you notice it, but don't give it much thought. Well, it turns out to have a dark connection to WWII.
