Simon Templar und der Doppelgänger.

The Saint

The Saint's hired by Greek millionaire Eugene Patroclos to locate the man who's impersonating him. However, when Templar catches up with the double, he's told he's the real Patroclos, not the man who originally hired him. Both men have secretaries named 'Annabel', and Simon must work out which of the 2 Annabels he trusts, to help him unravel who's the real-deal.
