Last week, the internet went crazy over Zachary Howell’s “Harry Potter” photo-shoot, and for good reason, as he is definitely the sexiest Potter to date.

Now he and photographer Sarah Hester are back with another steamy set – this time, they’ve turned Zachary into… a sexy Dexter.

Right in time for Halloween, Zachary and Sarah, along with Kaila Lauridsen collaborated for another one of what they call a “Dudeoir”.

The hunky Zachary was once again stripped off most of his clothes, and this time, instead of a wand, he was give a knife. The result? Breathtaking.
