One moment he was gone, and the next he seemed to appear out of the cold February air.

And this person turns out to be the twins’ nephew, Euler. Ian and Alexandra cannot stay away; now they will have to try to clear the name of their relative, find the real killer and understand the secrets of the past that led to the tragedy. It soon becomes clear that there is much more crime and death in this story than it seemed at first glance, and the road to the truth lies through a dark forest with a house of torture hidden in it...
