S. U. Wiemer
Pseudonym of Susanne Wiemer
Various Internet sources claim that the S. U. Wiemer novels were written by Susanne and Udo Wiemer. Jörg Weigand's "Pseudonymlexikon" in its 2nd printing confirms a collaboration only for the mystery series Jerry Cotton. Thus, "S. U. Wiemer" stands for "Susanne Ursula Wiemer", Ms Wiemer's full name.
