The Story

On December 1, 1948, an unidentifiable body was discovered slumped against the Somerton seawall. All clothing labels were excised, and he carried no identification. A hidden pocket yielded a torn scrap from a Rubáiyát of Omar Khayyám reading 'Tamám Shud' (ended). In 2022, DNA analysis resolved his identity as Carl Webb, though his cause of death and the cipher found with him remain mysteries.

Known Evidence

Evidence strength

How well-documented and physically verified the case evidence is.

  • Strands of hair extracted from a 1949 plaster death mask, yielding mitochondrial haplogroup H4a1a1a for genetic genealogy.
  • An abandoned brown suitcase at Adelaide Station containing custom-ground tools and clothing marked with 'Keane', matching Webb's sister's married name.
  • Autopsy profiles detailing extensive internal organ congestion and a swollen spleen without any trace of standard food or common chemical toxins.
  • A rare copy of the Rubáiyát featuring an uncracked five-line capital letter cipher (e.g., WRGOABABD) penciled on the back cover.

Unresolved

What We Still Don't Know

  • The definitive toxicological or chemical cause of death, widely suspected to be an ultra-fast-acting, undetectable cardiotoxin.
  • The true meaning or decryption key of the five-line alphabetical sequence written on the book.
  • Webb's precise timeline, operational motive, and movements from Melbourne to Adelaide immediately prior to his death.

Horse Racing Betting Shorthand

The mysterious capital letters were not an espionage cipher, but a highly personalized, abbreviated shorthand system used to track horse racing selections, a known hobby of Webb.
