It takes 27 years for justice to catch up with multi-murderer Carl Fredrik Wykman. No one has dared testify before, but a death-bed confession changes everything. How many lives are on Wykman's conscience? How many witnesses has he silenced? With the help of archived material, court records and coroners Eva Rudd and Katarina Howner and genealogist Leif Mörkfors, David Lagerkrantz breathes new life into an old criminal case.
