Andreas’s disappearance is a mystery to all, including his inseparable friend Zipp.  But Zipp finds it hard to tell the police the details of when he last saw his friend – they had been shadowing an old woman, an easy target for some quick cash and Andreas, brandishing his knife, had boldly followed her into her house.  And then he was gone.   Inspector Sejer and his colleagues are baffled, but while the confusion in the outside world continues, a chilling, heart-stopping drama is unfolding inside the old woman’s home. Appearances aren’t always to be believed, and people are not always what they seem.
