In 1989, Simon Dutton brought back the long-running character of Simon Templar, AKA The Saint, with a series of six two-hour action films, produced for (and originally shown on) television in the UK. The second feature in the series, The Blue Dulac, sees Templar en route to Paris, the City of Lights, where he uses the titular blue gem - once the property of the Russian czars - as the bait to trap a murderer and thief who loves to mix and mingle with the French aristocracy.
