"The Casual Vacancy," the mini-series based on J.K. Rowling's adult mystery, will land Stateside on HBO in April. The three-part show will premiere on BBC One on February 15.

In the meantime, there's a little teaser trailer to introduce us to the quaint British town of Pagford. It all looks veddy proper and jolly indeed, but naturally there are all sorts of grown-up, non-wizard-y secrets lurking just below the surface. However, it probably doesn't help that Dumbledore is part of the ensemble cast. Just saying. It also stars Rory Kinnear, Emily Bevan, Julia McKenzie, Keeley Hawes, Monica Dolan, and Abigail Lawrie. The adaptation was written by Sarah Phelps, who also penned scripts for "Great Expectations," "Camelot," and "EastEnders."

"The Casual Vacancy" was J.K. Rowling's first novel outside of the "Harry Potter" series. Her second, "The Cuckoo's Calling," was released under the pseudonym Robert Galbraith, although soon enough the author's real identity was revealed.

Check out the trailer below.
