cipher – Who destroyed my grandmother’s pillow?

Who destroyed the pillow?

The ferret did it!

What did the parakeet say?

The parakeet’s message is abnormal. It is composed of many repeated letters, 259 in general with the next distribution:

  121 × S   73 × U   57 × P   3 × H   3 × N   2 × D

What do the letters imply? We’re given a touch, that the alphabet might be symbolic. Hmm. Those letters might be chemical symbols, except for D. (D may imply Deuterium, however that isn’t how chemistry works right here on PSE.) The trace is given through any person referred to as Dottie. The letters have three- or four-signal Morse encodings. Changing them yields a message of 840 dots and dashes. Possibly we need to prepare them in a rectangle in order that dashes and dots make a pleasant development. In spite of everything, the puzzle is ready an embroibered pillow and the message may well be an embroidery development. Sadly, I could not get the rest helpful out of any of those concepts.

Here is a helpful remark:

The 3 N’s within the message are at positions 65, 130 and 195. That is an overly common development and we will divide the string at those positions to get 4 strains of equivalent duration:

SUUUUUSUSSSSSSSSSSUUUSSSSSSSSSSSSSSSSSUSSSSSSSSUSUSSSUSSSSUSUSSS
PUSSSUPSPUSUUUSSSPSSUPUUUSUUUSUUUSUUUPSPUSSSSUPSPUPUPSPSSPUPSPUS

SSPUPSPUPUPUUUPSSPUPSPUUUPUPSPUPSPUUUPUPSSSSPUUUPUPUUUPSSPUPUPSS

Let’s separate the letters for readability:

S.....S.SSSSSSSSSS...SSSSSSSSSSSSSSSSS.SSSSSSSS.S.SSS.SSSS.S.SSS
..SSS..S..S...SSS.SS.....S...S...S....S..SSSS..S.....S.SS...S..S
SS.S.S.SSS.S...SS.SS..S...SS..SS..S...SS..SS.S.S.S.S.S.SS.S.SS..
SS...S.........SS...S.......S...S.......SSSS...........SS.....SS

.UUUUU.U..........UUU.................U........U.U...U....U.U...
.U...U...U.UUU......U.UUU.UUU.UUU.UUU...U....U...U.U......U...U.
.............U......U...U...U...U...U...U.....................U.

................................................................
................................................................
............H..........H...........H..........D.....D...........
................................................................

Some patterns emerge: The P’s are best provide on each and every different column and the vertical stretches of U’s are the place the P’s are not. There are 3 thick columns of S’s. And the few H’s and D’s are best within the 3rd row.

What now? The road duration of 64 may imply that we need to rearrange every line right into a 8 ×8 sq., however that does not paintings.

Ah!

Needless to say we cut up the textual content into strains on the N’s? So successfully, we’ve changed every N with a New-line persona. Possibly the opposite letters constitute symbols, too? That may additionally have compatibility well with the trace.

Obviously, S method Stempo. After a little of experimentation, we get U for Underscore and P for the Pipe persona – that is what programmers name the vertical bar. All is apparent now, and we fill within the closing two: H for Hyphen and D for Dot.

Who destroyed the pillow once more?
