S4 AU from Rosie's POV. Mary didn't die because she managed to slap her hand over Sherlock's big fat mouth before Vivian Norbury pulled out her gun.


Five-year-old Rosie Watson's eyes were as big as saucers as Mummy finished her dramatic retelling of how she saved Daddy from the well while Uncle Sherlock was busy trying save his sister from hurting herself or anyone else.

"Wow," she breathed when Mummy finished by telling how Uncle Sherlock and Aunt Molly's wedding was because of everything that happened that day. "That's so neat! I hope I have fun stuff like that happen to me when I'm a famous doctor spy lady!" Her eyes lit up as Mummy and Daddy looked at each other with their 'uh-oh' faces. "Oooh, maybe someone will try to kill someone at MY wedding like they did at yours! That would awesome!"

She wasn't sure why Daddy had his scrunchy-face on, or why he sighed when he hugged Mummy, and she definitely didn't understand why he said, "Right, that's it. We're keeping her locked in her room until she's thirty."

Silly Daddy. Didn't he know Uncle Sherlock had already taught her how to pick locks in case of a 'mergency?
