There are few things that can ruin the New Year's mood more than freezing rain - perhaps only a suicide bomber who has to be removed from the eaves of the roof. Australian federal police investigator Sandra Morris can barely cope with this when she and her partner are sent to investigate a sinister and dangerous case: it seems that a madman has visited an ordinary Moscow high-rise building. The death of a young girl was turned into a ritual, there were even too many suspects - the personal life of the deceased was turbulent. However, Sandra and Ian suspect that this story is much more complicated than it seems. This means we need to hurry up with the investigation before new victims appear.
