A secret summit of superpowers is to be held in Baghdad, but it is no longer secret. A shadowy group (which is both anti-Communist and anti-Capitalist) is plotting to sabotage the event. Things get complicated when enthusiastic young "adventurer" Victoria Jones discovers a dying secret British agent – Henry "Fakir" Carmichael – in her hotel room. His last words – "Lucifer...Basrah...Lefarge" – propel her into investigation. "Lucifer" refers to the mastermind, Victoria's false lover Edward, who is behind the plot. "Basrah" is thecity where Carmichael saw Edward and recognised him as an enemy. "Lefarge" turns out to actually be "Defarge" and is a reference to a Charles Dickens character; it is an allusion to the fact that the name of a vital witness has been stitched into a scarf.
