OMG THIS WAS...I HAVE NO WORDS!!! Sherlock and Inception? that's a crossover I would never have thought of and you made it work so damn perfectly. The characterizations were SPOT on and this bit was def. my favorite;

“I like him,” Arthur said.

“You would. He’s got even less imagination than you,” the man with the briefcase stated, finally clipping the case shut and standing casually.

Now that bit of dialog is something that's so true to these two it's canon. :D
