New seasons of Castle and Body of Proof are to air on UK satellite channel Alibi.
Alibi has already shown earlier runs of the shows and has agreed a deal to transmit the fifth and sixth seasons of Nathan Fillion's fun crime drama.
A third and potential fourth season of Body of Proof is also part of the deal, making Alibi the first UK channel to premiere new episodes of the hit shows.
"Castle and Body of Proof have been huge successes both Stateside and in the UK and this deal ensures Alibi remains a must-have channel for all fans of crime drama," said UKTV's head of acquisitions and co-productions Alexandra Finlay.
Castle season five will debut in March, while the Dana Delany-led Body of Proof will follow in July.
