After all of the drama and intensity of the two-parter that concluded with Castle Season 7 Episode 15, we think it's time for some fun.
So when an astronaut turns up dead in a Mars simulator next Monday evening, Castle, Beckett and the team don a whole new look to investigate the case. That's right, space suits!
We look forward to hearing Castle declare this the "best case ever," as this has to be something straight out of his childhood fantasies.
Check out these photos from Castle Season 7 Episode 16, "The Wrong Stuff," which scheduled to air Monday, February 23 on ABC.
Don't miss a minute of the fun. You can watch Castle online now right here at TV Fanatic.
