This incorporates my original Zodiac Z13 solution into a three part musical score.

The source material is the 1957 D’Oyly Carte recording of that musical. The z13, the hole punch and the z32 provide a meta 1.1 fit. The musical references are the z32 code as he would have heard them whilst listening to his record.

It is a mechanical solution rather than traditional coding dogma. I filtered out irrelevant speculation and solved it as if it was a video game puzzle. This enabled me to cut out the noise and test the evidence as it presented itself. I wasn’t aware of the Mikado or hole punch until I started to piece it together.

Yes, it was done with ai, but I am not ashamed to utilise the tools available to me.

Some of you might be aware of my Z13 solution I previously posted. This is for the 32. I would have done it faster but I forgot there’s a lot of spoken words in musicals as I rarely watch them. After I remembered this I managed to solve the 32 in less than an hour, which is decent. Anyway, the solution is from the spoken word sections that appear in the accompanying booklet to the 1957 D’Oyly Carted recording that I used to solve the Z13. I’ve included the solution plus the prompts Gemini Ai gave me to enable Grok to recognise the methods I used. Im aware it’s disappointing to those looking for a name but he was never going to walk into the police station with handcuffs and spit the key down the drain on the way in.

By using the 1957 Mikado vinyl recording and including the notes sung by the backing singers as heard by the killer I have solved the cipher. It doesn’t contain a name, but the first letters of 13 lyrics of the List song fit mathematically perfectly. The song is sung by The Executioner, which is the persona the zodiac has taken, so his letter will say My Name is The Executioner followed by the mocking words from the song. The 13-hole punch fits perfectly where the three Be lyrics appear which acts as a key. It only works with the 1957 vinyl print as the sheet music only contains the Executioner’s lyrics and not the backing singers too.
