While storyline on Castle can also veer from the ridiculous to the realistic, the ABC hit will focus on the personal this winter.
Producer Andrew Marlowe tells TV Guide his show will return to the issue of Beckett's murdered mother in January.
"There will be some closure; we'll have some understanding as to exactly why Joanna Beckett was killed," Marlowe says. "The audience will find out how high the conspiracy goes and the elements that we're dealing with. I think it can provide us with an interesting insight into [future] storytelling."
And where will fans find in-depth coverage on these episodes of Castle? TV Fanatic, of course!
