I received the letter

You create the intrigue

The letter arrives without revealing your identity and leaves a first clue to begin.

The story advances automatically

Speak without exposing yourself first

They don't receive a cold message

You don't have to guess what happened

How it works

You start the mystery. The other person decides how far they want to play and respond.
