Harry Dresden is the best at what he does. Well, technically, he's the only at what he does. So when the Chicago P.D. has a case that transcends mortal creativity or capability, they come to him for answers. The "everyday" world is actually full of strange and magical things - and most of them don't play well with humans. That's where Harry comes in. Takes a wizard to catch a - well, whatever.
There's just one problem. Business, to put it mildly, stinks. So when the police bring him in to consult on a grisly double murder committed with black magic, Harry's seeing dollar signs. But where there's black magic, there's a black mage behind it. And now that mage knows Harry's name. And that's when things start to get … interesting.
Magic. It can get a guy killed.
