Ideal dinner party guest Maite Karssenberg is an expert in an endlessly flowing stream of subjects. The author of a biography on the fascinating freethinker, intellectual and publicist Geertruida Kapteyn-Muysken, Maite has also written a travelogue detailing Iranian mosaic art which has been translated into Persian. When not at her writing desk, she can be found working at the Amsterdam bookshop Athenaeum. ‘On Demand’, her erotic short story for Extra Extra no. 19, centres on a chance, voyeuristic encounter.
