Exhibition design for Det Hemmeligste 

Det Hemmeligste Af Det Hemmelige is a Danish podcast diving into the world of intelligence agencies, spies, financial crime, true mysteries — and most famously, the murder of Olof Palme.

In collaboration with their producer, Rebecca Angiulli, I designed their exhibition space at the fair Historiske Dage 2025 in Øksnehallen, Copenhagen. The space is inspired by Palmerommet, a room within the Stockholm police station solely dedicated to work on solving the murder of Swedish Prime Minister Olof Palme. The design challenge was to convey the notion of a detective's office from the 80s while at the same time capturing visitors' attention from afar and giving a clear idea of what the podcast is about – without necessarily having to enter the dedicated 9m². Øksnehallen was sold out and the exhibition was a success.
