Castle and Beckett can't seem to escape crime, no matter where they go -- or what they're doing.

HuffPost TV has an exclusive sneak peek at next week's "Castle," titled "Murder, He Wrote" (Mon., Oct. 15, 10 p.m. ET on ABC), which finds our finally-together and finally-alone friends getting frisky on their Hamptons vacation. Who knew Beckett (Stana Katic) was the skinny dipping type? But the evening takes a turn when death comes walking right into the pool at Castle's (Nathan Fillion) vacation home.

Watch the clip above to see what happens. Fans of the old near-kiss tension with this crime-fighting duo should enjoy the suspicious interruption. When will these two ever catch a break?

"Castle" airs Mondays at 10 p.m. ET on ABC.
