In the first moments of Monday’s (21 February) show, however, viewers noticed that this week’s episode instead featured three contestants and an empty chair.
One viewer described the incident as “the most dramatic OPENING scene of an episode of Mastermind EVER”.
Fans of Mastermind were thrown a curve ball at the start of the latest episode, when they noticed one of the contestants had “gone missing”.
The format of the popular BBC quiz show calls for four contestants to compete against one another in rounds of general and specialised trivia.
