The additional pickup will bring the total third-season order for the show to 24 episodes. While not a breakout hit, Castle has been a solid performer for ABC on Mondays where it runs neck-and-neck with CBS' Hawaii Five-0 for the top spot in adults 18-49 at 10 PM.

...I think ABC wanted to extend it to just "one and a half" {"What are we supposed to do with the other half?"/"Can't you just throw everybody in the dark, and improvise? You know, like radio..."/"We're not doing a radio show!"/"Look, we told Jimmy Kimmel this, and now we're telling you: unless you find more corporate sponsors to 'weave' their products into your show, we can't afford to pay for more episodes."/"'DESPERATE HOUSEWIVES' isn't doing as well as we are, yet you're giving them more money!"/"Get more sexier women on your show, and we'll see what we can do."}. Such is the business of television....
