Chief Inspector Sara Vallén receives a tip that could help solve a 20-year-old cold case about a two-year-old boy who disappeared from his preschool without a trace.

Meanwhile, Sara's daughters Klara and Bella are being harassed by a group of young Nazi sympathisers for starting a student association supporting unaccompanied refugee youths. One of these youths, Reza, is found dead in Höje with a swastika carved into his forehead. A hunt for the killer begins while Vallén and her colleague, Torsten Venngren, follow up on the new lead on the missing toddler.

A dark, fast-paced, crime thriller with a finger on the pulse of today's social climate, "Without a Trace" is the exciting third instalment to the Sara Vallén series.
