We Don’t Do Murder – A puzzle-based murder mystery

On one of the long afternoons, Mieke asked Mumford how it all began – The Absent Answer, and everything that lay behind it.

Mumford thought for a moment. She said, ‘I haven’t always investigated murders. I was drawn into it.’

She said it was hard to say when her first case really started. Maybe it was when she found a message, disguised with the simplest of ciphers.

Dear Mumford,

G P V M E F F E T X J M M S J T F *

Then Mumford said, “Actually no, that’s not right. It really began before that.”

She promised to think about it and write something down.

She said it would take a long time.

Here is the solution to the riddle above.
