That is Mrs. Peacock DR TCB. And yes there is a total of 216 different combinations - at the beginning of the show, audience members choose three cards......suspect, room, weapon.....just like in the game.
And the secret chosen cards are put in a big envelope - and depending on what was chosen....those are the way the scenes/songs are presented....the audience plays along - just like the board game - to see if they can discover the solution.
