Just to clarify this is NOT a crossover. It's just Sherlock and Watson (+Mary) in New York. No connection with Elementary.
Chapter 1
Molly closes the front door on 221 B. From the stairs she hears a strange sound. It almost sounds like music but it's not coming from any instrument she can identify. She makes her way up the stairs and into the front room. Sherlock sits on his chair with dozens of bowls in front of him stacked inside each other. Sherlock runs his finger around the rim of the bowls to create different tones.
"Sherlock."
"Molly." Sherlock says without looking up.
"Are you alright?"
Sherlock finally looks at her. "John sent you to make sure I wasn't bored."
"Yes. How did you know?"
"Lestrade came yesterday."
"Oh."
"You don't have to check up on me. I'm fine."
"Is that why your playing the…"
"Armonica"
"Excuse me?"
Sherlock points the the bowls. "Armonica. Derived from the greek word Harmonica, meaning Harmony."
"You're bored aren't you."
Sherlock just looks at her.
"You need a case."
Sherlock starts to wander around. "There is nothing interesting happening. Nothing in the entirety of London. Just normal people going about their business. Don't they understand how boring their lives are?"
Molly sits down in front of the computer. She scrolls thought Sherlock's inbox.
"It would be interesting if John and Mary were here." He says.
"My children's toy robot moves when we're not home."
"Animatronic, motion sensitive. Set off by the dog."
"What about this one?" Molly reads out the email.
"Dear Mr. Holmes,
My sister died twelve years ago on September 11, 2001. Three weeks ago I received a letter claiming she is still alive. It was accompanied by photographs of a woman who looks just like my sister. I need to know if these pictures are real, and if they are, where is my sister?"
Sherlock turns and walks straight to the computer.
"Brilliant. You know Molly Hopper sometimes you exceed my every expectation of you." Sherlock goes to his room.
"Thank You?" Molly turns back to the computer. "Wait. Sherlock this isn't in London. He's in… Sherlock!"
Just a little opening teaser. I should have more in a few days. Please let me know what you think.
