Blake & Mortimer: The Yellow M (1970)

Sinopsis

Europe, 1941. Nazi Germany develops the Omega Wave: a dangerous mind-control weapon capable of bending human will. MI5 Captain Blake and physicist Mortimer join forces to destroy it. The lab goes up in flames and the weapon is lost… or so they believe. Twelve years later, in 1953 London, a string of unexplained deaths grips the city. A shadowy figure known as “M” surfaces, armed with the Omega Wave. With the Queen’s coronation days away, Blake and Mortimer, two old friends, reunite on a deadly mission.
