Once upon a time, a man was imprisoned by a corrupt leader in a cellar. Every day, a servant would come by and give him a singular piece of bread. One day, he was given a note. On the note, there was written a line of letters:


What happened, and what should he do?

  • $\begingroup$ Yeah. You're right. It was a D sorry. It's been fixed now. $\endgroup$

    $\begingroup$ Preferably wait for a day first; there are solvers in various time zones, and the puzzle hasn't been yet seen by most of them. $\endgroup$

Here's what you should do:

At noon in two days, climb out the trapdoor.

The note ...

... is enccrypted with a btransposition cipher. The message is 42 characters long. Rearrange them in three lines of 14 characters:

    A N N N W D S L B U T • A O
    T O • • O A • I • T H T P O
    • O I T • Y C M O • E R D R
Now read the message column-wise. The dots are spaces.

  • $\begingroup$ Fitting that you waited this long. ;) $\endgroup$

    $\begingroup$ Yes, but here it's closer to midnight than to noon. (That gives me more than 12h to find the trapdoor.) $\endgroup$

    $\begingroup$ Good job. I didn't even know that btransposition cipher was something. I thought I had made it up. Thanks for showing me that I didn't make it up. $\endgroup$
