My research into this author revealed little other than he supposedly based this book on his wartime experiences fighting for the Danish resistance. He would go on to write the 22nd novel in the series, The Stone-cold Dead in the Market Affair. However, I could find no other novels by him, or any other pen names he might have used.
This is a quick read, with a straight-forward plot that seems a lot like one of the season one television shows. Solo still gets most of the protagonist role but I did notice Kuryakin seems to be a bit more of a ladies man than we see in the TV show. Perhaps, like the first two books in the series, this was written based on the show’s concept and before the show’s first scripts were produced or maybe just before the show started to jell into its norm. David McCallum, the actor who played Kuryakin, is on record as saying he purposely did not play the role as a ladies man, believing the character would be too focused on the missions to get side-tracked by that.
