DeKok and Murder on Blood Mountain

At the request of the Belgian police, Inspectors DeKok and Vledder attend the funeral of a murder victim. The body was fished out of Antwerp’s Scheldt River, but brought back to Amsterdam to be laid to rest there. During the service DeKok spies the face of a man long known to be dead.
Further bodies are discovered, apparently they too were poisoned and dumped in the river. DeKok is forced to venture from his beloved Amsterdam and travel to Bloedberg (“Blood Mountain”), a notorious neighborhood in Antwerp, to continue his enquiries.
