Deliciously Dark Dexter (TM Tube Talk, 2007) is about to return for its fourth killer season. The last we saw, our favourite serial killer got hitched to long-time girlfriend Rita and vowed to be "the best father and husband" he could be. So what next? Digital Spy's resident soaps expert and Dexter überfan Kris Green presents Ten Tantalising Teasers (TM Tube Talk, 2009) about the season four premiere:

1. Season four picks up six months after the end of season three. Dexter and Rita are now living a suburban life with their new son Harrison - named after Dexter's father, Harry.

2. Quinn begins to doubt Dexter's integrity when he bungles his blood evidence in the Benito Gomez murder trial.

3. The first crime scene of the series is literally a bloodbath.

4. Deb's still loved up with police informant Anton Briggs, but the return of an old face reignites old feelings.

5. Rita brandishes her tickling stick for a saucy sex session with a weary Dexter who attempts to squeeze in a pre-coital power nap.

6. Dexter lets the only person he can tell in on his secret - he's now "killing for two".

7. LaGuerta has sexy time with a surprising series regular.

8. Dexter erects a killing room in a boxing ring in an abandoned warehouse, before making his first kill of the series.

9. The Trinity Killer - real name Walter Simmons, played by John Lithgow - is apparently partial to a scalding shower.

10. And the episode ends on an almighty cliffhanger in which you wonder how even Dexter could dodge the scenario that inevitably ensues…
