DeKok and the Geese of Death

DeKok takes on Igor Stablinsky, a man accused of bludgeoning a wealthy old man and his wife. To DeKok’s unfailing eye the killing urge is visibly present in the suspect during questioning, but did he commit this particular crime?
All signs point to one of the few remaining grand estates in Holland. The answer lies within a strange family, suspicions of incest, deadly geese, and a horrifying mansion.
