Apartment Carpet

When I was a child, this game was in the magical cabinet of "grown-up things" that also included poker chips and Jack Daniels. I had forgotten all about it until I saw it on 2 (count 'em!) websites in the space of a week. Somehow, the game is intimately connected in my mind with the Agatha Christie's Poirot series that aired on PBS. I can think of no rational explanation for this. I never actually learned to play the game, and I didn't watch the tv show.
