Troubles of Rosamund Mary Watson Holmes

Pilot chapter

Hush little baby, don't you cry
Daddy John is ready to save your life

It was a warm summer night, no one expected anything bad to happen in the Holmes family in 221b Baker Street. Little Rosa, now five years old, was peacefully sleeping in her parents' bedroom. Room window slowly creaked open and gentle breeze moved the papers from John's table and some even fell on the floor.

Hush little baby and look at sky blue
There's Mama Mary watching over you

Sherlock and John are in the living room, reading some files. There has been multiple strange cases in last week and Sherlock finally agreed to help Greg to solve them. Family pictures were covering every possible surface in there. From the ones of just them, to ones with Sherlock's family, Rosa and Mycroft, Mary with just born Rosa, and many many more. The open window behind Sherlock slowly closed and the draft was obvious in the room. Their bedroom door made a sound like they were about to open, but wind has no hands and it can't turn the knob. Who left the window open in their room? 

Quiet little baby just stay still
Sherlock really loves you and always will

Rosa felt like flying. She felt in her dream, someone holding her, but she was dreaming of her mum, so she didn't mind the feeling of her apparent hug. But it wasn't mama Mary. Oh, no. No no no. Rose woke up with a wish to scream, but there was a hand covering her mouth as her head was in this person's lap. She heard him sing the song that echoed through her dream.

Hush little baby don't make a sound
Uncle Moriarty has got you now...

She was afraid to move, afraid to make a sound, knowing well from what she sees and hears, that she is on the back seat of someone's car and that no one will be able to hear her now. She might as well not piss off her kidnaper.

John went to see what is happening in the bedroom and as soon as he saw the empty bed and wide opened window, his whole world collapsed. As he told Sherlock that Rosa is gone, they started searching for her, they called Greg, they searched first the whole house and then the whole street, but Rose was not there. 

Sherlock stood devastated in the middle of the bedroom when he noticed smudges on the window. He quickly closed it and blew hot air from his mouth onto the smudges. Two words, six letters, appeared as he did so and cold sweat covered his body. John found him staring at the window and as he read what stood there, he joined his husband in this action. They knew who took Rosa. And they knew that this is not just a random kidnapping act. 

On their bedroom window, only visible due to condensation, stood a well familiar phrase.

Miss me?
