The Arora Investigation series follows its titular investigator through six books of Icelandic crime fiction. The color-themed English titles — Cold as Hell, Red as Blood, White as Snow, Dark as Night, and Black as Death — give the series a visual identity tied to Iceland’s harsh climate and long winters.
Published between 2015 and 2025, the series has grown from a domestic Icelandic success to an internationally translated property. Each book sends Arora into a new case that peels back another layer of Icelandic society.
