Hard Rain

Description for HARD RAIN by Janwillem Van De Wetering:

Few would mourn the apparent suicide of Martin IJsbreker, banker for the Society for Help Abroad--a clever front for an international vice ring, led by none other than the commissaris's boyhood rival, Fernandus Willem. If the commissaris could prove that Ilsbreker was murdered, he could begin to wipe out Fernandus and his filthy doings forever. But even Grijpstra and de Gier are little help when the commissaris's plan to destroy his nemesis suddenly threatens their jobs, their loved ones, even their lives....

This is #11 in A Grijpstra and de Gier Mystery Novel.
