Colonel Alexander "Alex" Mandraki was a ranking member of the Greek army.
In 1922, Colonel Alexander Mandraki took part in an elaborate assassination attempt against King Constantine. Mandraki and his co-conspirator—and secret lover—archaeologist Dorian Belecamus planned to pin the deed on one of her third-year Ph.D. students, Indiana Jones. The plot went awry, and Mandraki was killed by the king's guard.
