5. The Secret Weapon of Doom
After an unfortunate bathchair accident, Professor Dunning (Terry Molloy) is temporarily invalided out of the Secret Service. But returning to his first love, writing, proves more perilous than expected.
Meanwhile, unhinged MI-13 chief Colonel Black (Leslie Phillips) has a new case for Lionheart (Nicholas Courtney). Partnered with top spy - and housewives’ favourite - Victor Bright (Nigel Havers), Lionheart investigates the disappearance of a fabled super weapon - and discovers they aren't the only ones searching for it...
Death stalks our heroes at every turn. Lionheart and Dunning must fight for their lives as dark forces gather around the mysterious SECRET WEAPON OF DOOM.
