That refers to the killing of gangster Mr. Solo in Goldfinger ....... That naming him Solo was a swipe at The Man From Uncle on TV at the time, that had Robert Vaughn as Napolean Solo. This was known by movie goers (and me) back then. It is no mystery, sleuthed out via today’s internet.
I fervently watched The Man From Uncle. David McCallam as Illya Kuryakin and Leo G. Carroll as Mr. Waverly.
