Spies named Black

"Black" is for spying. Something very secret is a "black project."

I have been amused at finding top spies named Black. William B. Black, Jr., rose to Deputy Director at the National Security Agency. And Coffer Black spent 28 years at CIA, eventually heading their Counterterroist Center. Then, to add one more irony, he became chairperson of the private security company Blackwater USA which has been in the news in Iraq.
