Newsflash, Einstein: Your Mensa membership card was not lost in the mail.

But having mastered Sudoku, road maps, and that universal remote you got for Christmas, you might be ready for a new challenge.

Pegasus Theatre’s Mind over Murder! can give your genius-in-the-rough I.Q. something to think about. The simple story involves a well-intentioned detective named Harry Hunsacker who tries to solve a mystery. But there’s a complicated twist: It’s presented in “living black and white,” which means the entire three-dimensional play is modeled to look just like a two-dimensional black-and-white television show.

How do they do it? Well, everything on stage — costumes, makeup, even props — is black, white, or a shade of gray. The illusion is impressive. As you will be when you explain it to your friends.

Now that’s using your head.
