I don't get it.

Who is she?

I stared at the woman sitting in front of me, in my chair. MY chair!

"Oh hey, didn't see you there." Her head lifted up from the book she was reading.

Grimms' Fairy Tales

"Who are you?" I arched my eyebrows and took my coat off in the process.

"Oh me?"

"Yes you, who do you think I'm talking to?"

"Him." She gestured to the door.

As if on cue, John walked in. I looked at him in the eye as he spoke.

"Who were you talking to Sherlock?"

"Her!" I turned around and pointed towards my chair.

There was no one there. No one. The only thing remaining on my chair was the book she was reading.

Grimms' Fairy Tales.
