Here we have three tantalizing TV teasers for fans of some of the hottest shows today: Showtime’s Homeland, AMC’s Breaking Bad, and BBC One/PBS’ Sherlock. Warning: spoilers within!

Above, the Homeland teaser titled “Signals” begs the question: Where is Brody? At the end of season 2, a car bomb destroyed the CIA and it was made to look like Nick Brody was behind the devastating attack. Carrie, of course, believes him when he says he didn’t do it and she helps him escape the country. “Does Carrie know I’m here” is just one of the many “signals” broadcast in this 30-second teaser that unfortunately shows zero footage from season 3. Homeland returns September 29.

After the break you’ll find the teasers for Breaking Bad and Sherlock.

Bryan Cranston as Walter White reads the entirety of Percy Bysshe Shelley’s sonnet Ozymandias in this teaser hyping the final run of the acclaimed series. According to Wikipedia, the central theme of the poem “is the inevitable decline of all leaders, and of the empires they build, however mighty in their own time.” Will Walter’s world come crashing down upon him now that Hank knows his dirty little secret? Perhaps this teaser–which also includes beautiful shots of locations from the show–is a telling sign of what’s to come. Breaking Bad returns August 11.

Sherlock pulled off quite a feat last season when he managed to survive a long fall off a tall building. In this teaser that is too short, Sherlock returns from “the dead” to reveal himself to a mustached Watson in a restaurant. Fans will have to wait to see John’s reaction when Sherlock returns sometime in 2014.
