I'd like to nominate Halting State by Charles Stross.

In the year 2018, Sergeant Sue Smith of the Edinburgh constabulary is called in on a special case. A daring bank robbery has taken place at Hayek Associates, a dot-com startup company that's just been floated on the London stock exchange. The suspects are a band of marauding orcs, with a dragon in tow for fire support, and the bank is located within the virtual reality land of Avalon Four. For Smith, the investigation seems pointless. But she soon realizes that the virtual world may have a devastating effect in the real one-and that someone is about to launch an attack upon both...

It was called in as a robbery at Hayek Associates, an online game company. So you can imagine Sergeant Sue Smith's mood as she watches the video footage of the heist being carried out by a band of orcs and a dragon, and realizes that the robbery from an online game company is actually a robbery from an online game. Just wonderful. Like she has nothing better to do. But online entertainment is big business, and when the bodies of real people start to show up, it's clear that this is anything but a game. For Sue, programmer Jack Reed, and forensic accountant Elaine Barnaby, the walls between the actual and the virtual are about to come crashing down. There is something very dangerous and very real going on at Hayek Associates, and those involved are playing for more than experience points. No cheats, no extra lives, no saving throw - make a wrong call on this one and it'll be more than game over.
