Crossover: The Holy Grail Splashed Black Mud All Over Me

I had the mother who loved me more than anyone else in the world.

But that was in the past.

Because of my arrogance and recklessness, I left my hometown and became lost among different worlds, never able to find my way home again.

Whenever I think of how heartbroken my mother must be over my sudden disappearance, I wish I had died back then. At least a corpse would only make her grieve for a while. A daughter whose fate is unknown would leave her clinging to a hope she should never have had.

My name is Kayden. I'm the daughter of the criminal mastermind Moriarty, and I'll give up everything if it means returning home and seeing my mother again.

The heroine is Moriarty's daughter from Elementary. She travels through countless worlds and leaves a trail of broken hearts in her quest to get home and see her mother. Then the Holy Grail plays a huge joke on her: she really does return to the world of Sherlock Holmes, but it's Sherlock, not Elementary.

Kayden says she's having a bit of trouble accepting a world where her beloved mommy and her stepmother have both become men.

Kayden comes from a world that brings together characters from various American TV dramas, but the world she's in now brings together British TV dramas... So let's applaud Moriarty: she's a woman who managed to become the ruler of the criminal underworld in a world with the BAU, Carter, Bones, CSI, and all sorts of unusual crime-drama protagonists.
