Puppet On A Chain. 1971.
Sven-Bertil Taube plays the U.S. Agent sent to Amsterdam to investigate a heroin smuggling ring after 3 agents are killed in a professional hit. This was a mix of James Bond even though Vladek Sheybal played a villain in a Bond film and a touch of The French Connection. Using Amsterdam as the main focus where drug use is rife and the red light district is a good setting but think the film is known for the epic boat chase that was probably inspiration for the Dick Maas 1987 movie. The film manages to keep a steady pace.with a few twists and turns added in for the suspense. One I'd certainly come back to view, even though some of the visual effects are a bit out of date.
