This was the second armchair treasure hunt book I discovered after Masquerade. Unlike Masquerade, I found it when it was new, just as the three year countdown for solving it started ticking. Of course I bought a copy straight away.
Certainly the book sets its stall pretty plainly, with its gold enlaced cover and its promise of a pot of gold and a garish gold wand for a clever winner. Rather than a buried treasure, the wand was safely locked away in the vaults of the Bank of England and solutions were to be mailed in.
Its astrological and chemical symbols immediately appealed to me and there was some fun to be had spotting patterns and linked figures.
