How it begins

The first letter arrives on a Tuesday. Your name at the top. A voice from another century.

"I've chosen you. Not for the reasons you fear — or not only for them."

Folded inside: a printed case note, styled after an 1888 newspaper report.

Except the street named in the report… is yours.

Eight infamous names. Twelve letters. One correspondent who knows far too much about you.

What arrives in your mailbox

Evidence, delivered every two weeks

How the choices work

Twelve letters. One guess.

I

Scan the QR in each letter to log clues and theories.

III

At letter 11 your final guess locks in.

IV

Letter 12 reveals the truth, and how many readers solved it.

Who it's for

True crime podcast listeners, escape room fans, murder mystery night hosts, and anyone who's ever said "I knew it was him."

You might be wondering

Fair questions

"Is it gory?"No. It's psychological suspense and detective work, not violence.
"Is it disrespectful to real victims?"The cast is limited to figures from centuries-old history and folklore. Victims are never used for shock value.
"Too hard?"The clues build steadily, and a hint letter is available.
"Can I solve it with friends?"Yes. Book clubs and sleuthing partners are encouraged.
