Bones returns with an all-new episode tomorrow night, entitled "The Male in the Mail." As you might have guessed from the title, some poor guy gets dismembered and packaged up at the local post office!

The Jeffersonian team soon identifies the victim as an employee of a local Ship 'n' Print, where the staff recently split the winnings of a lottery prize. There's potential motive ... but what about the means?

Hodgins has one theory, while Booth and Brennan happen upon an unlikely murder weapon at the scene. There's also a love triangle involved in this postal caper, which Booth is having trouble focusing on.

That's because his grandfather (Ralph Waite, who's always great as Booth's "Pops" and Gibbs' father on NCIS) stops by D.C. with some unexpected news that throws Seeley for a loop. What does he say?

Check out three sneak preview clips of tomorrow night's episode below and see:
