Bones promised to introduce a "21st Century, tech savvy adversary" in Season 7.

It looks like next week, on the delayed midseason finale, we may meet that foe.

In "The Crack in the Code," the Jeffersonian team investigates a murder scene at a national monument (the Lincoln Memorial, it appears), but the only clue left is a coded message made of human blood. Obviously.

This case is only the beginning of a scavenger hunt for the solution, courtesy of their new, technologically-proficient foe. Elsewhere, Booth and Brennan continue down the road to domesticity, looking for a new home.

Sadly, this episode - airing Thursday, January 12 at a special time, 8 p.m. EST - is Bones' last until the spring. The Finder spinoff will fill in from January 12 at 9 p.m. until Bones returns in March or April.
