A Real Honest to Goodness Burglar

Bilbo is a Thief, and a superb one at that! Life has been nothing but cruel to him, and he takes work as he can find it. It works pretty well, and he survives at least. But then he's hired by Smaug to steal the Arkenstone from Erebor. An impossible mission, but one he must accept. Unfortunately, things never do go as planned. Starts out pretty tame, but it will be M in the future.
