ABC has released the official synopsis and a batch of promotional images for the 100th episode of Castle, airing this Monday, April 1st. Castle is stuck at home witha broken leg and finds himself suddenly thrown into a murder mystery that hits close to home, literally.

• 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,
