It’s no April Fools’ joke. Not only does tonight mark the 100th episode of Castle, but it’s also an exciting homage to Alfred Hitchcock’s classic film, Rear Window.

In “The Lives of Others” Richard Castle is stuck at home with a broken leg and a massive case of boredom. Luckily, crime and sleuthing follow him everywhere, even when he’s not moving.

Check out the official synopsis below:

In the show's 100th episode, Castle finds himself in the unfortunate position of NOT being able to work a case. While he's holed up in the loft with a broken leg, Beckett goes off to investigate the death of an IRS agent without him, leaving Castle miserable and bored. But when he thinks he witnesses the murder of a young woman in the apartment across the street, he is thrown into a Rear Window-esque murder mystery that hits much too close to home.

So put on your “Writer” bulletproof vests and raise a glass to 100 fabulous episodes tonight, because life is good and television’s best couple is together forever (Caskett 4 Lyfe).
