An opium smuggling ring starts to operate across Europe, with its source in Turkey. Duval flies to Istanbul, where the local police have a suspect in the owner of an import-export business - except he appears to be operating quite legitimately. Finding a link in the supply chain gives Duval his first break, but leaves him with a problem: he must find a way of exposing the masterminds behind the scheme.
