“… I don’t know who it is, but come in.”

As someone knocked on the door of the boarding house at 221B Baker Street, where a chilling atmosphere lingered unlike usual, Charlotte, sitting quietly in an armchair, spoke in a low voice.

- Creak…

“It was you who called me here, wasn’t it…”

“… That aside, it’s unexpected.”

“What is?”

“It’s quite surprising that even after such a big event, no syringes are rolling around on the desk, nor is there even a hint of tobacco smell.”
