Frankie Muniz by John Shearer/ Frankie Muniz by John Shearer/

Don't tell Lois, but Malcolm has found himself in the middle of a murder investigation!

Reliable sources confirm to me exclusively that ex- Malcolm in the Middle whippersnapper Frankie Muniz has been tapped to appear in a November sweeps episode of Criminal Minds. The now-21(!)-year-old actor plays a famous comic-book artist who becomes involved in the search for a serial killer in Los Angeles.

I seriously hope "becomes involved in the search" isn't code for "becomes a prime suspect." Turning Dawson Leery into a modern-day Norman Bates was one thing, but Malcolm?! That would be a little creepy even for me. And I like creepy.

Muniz' episode is slated to air on Nov. 28.
