Here's ABC's official description of "Castle," "The Lives of Others":

"The Lives of Others" -- 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.
