Square One TV was a math oriented education show during the late 80’s and early 90’s on PBS. I loved catching the show whenever I could after school. It was a show full of short sketches – one of the regular ones was Mathnet – a mathematical parody of Dragnet.

In one episode – they hit 2 of my favorite things: math and spooky mysteries. They parodied Agatha Christie’s “And Then There Were None” in the episode “The Case of the Mystery Weekend“.
