I’ve started posting the Sherlock/Lie to Me crossover I’ve been working on for a few months, now. The first two chapters (villain setup and establishing how things have fallen out post-Reichenbach) are up, and I’m most of the way through writing a confrontation between Cal Lightman and Mycroft Holmes. It can be found here:
Moriarty was a diabolically elegant puzzle, but Sebastian Moran is a maddening and contradictory enigma. Not even Mycroft Holmes has any idea of who Moran really is or what he truly wants—or just how far he will go to carry out Moriarty’s final orders.
Then, during the investigation of a bizarre and brutal murder, Sherlock crosses paths with another unconventional genius who may be able to help him get to the truth about Moran. Unfortunately, Cal Lightman also holds the key to another truth, and for once in his life Sherlock Holmes finds there are some things he would give anything not to know.
