The second book in Edgar-nominated Anne Holt's international bestselling mystery series featuring detective Hanne Wilhelmsen, last seen in Blind Goddess .
IT is only the beginning of May but in Oslo a brutal heat wave has coincided with an alarming increase in violent crime. In the latest instance, police investigator Hanne Wilhelmsen is sent to a macabre crime scene on the outskirts of town. An abandoned shed is covered in blood. On one wall an eight-digit number is written in blood. There is no body--nor any sign of a victim. Is it a kid's prank or foul play? Is it even human blood?
As more bloody numbers are found in isolated locations throughout Oslo, Hanne's colleague H#65533;kon Sand makes a startling discovery: the digits correspond to the filing numbers of foreign immigrants. All are female, all are missing. Is there a serial killer on the loose in Oslo? How does the killer have access to immigrant data?
Meanwhile, as the trail heats up, the victim of a horrific unsolved rape case and her father have each decided to take justice into their own hands. Hanne and H#65533;kon soon discover that they aren't the only ones on the hunt for the killer.
