An episode of "Castle" with a bomb theme has been rescheduled by ABC following the tragedy at the Boston Marathon on Monday, reports EW.com’s Inside TV.

Instead of airing the episode "Still" on Monday, the network will air another new episode called "The Squab and the Quail," which was slated to air the following week. In that episode, Beckett protects a billionaire whose life is in danger, the story says.

The bomb-themed “Still” has been rescheduled for a week later, April 29.
