003/and The Carpathian Dog

It's haunted here! With this desperate exclamation from Mr. Prentice, a new adventure begins for the three ???. An adventure that becomes increasingly complicated, during which even the usually super-smart first detective, Justus Jonas, finds himself completely in the dark for a while. What eerie figure is coming and going in Mr. Prentice's apartment, instilling greater and greater fear and terror in him? What is the source of those ghostly flashes of light in his study, six meters above the street? Who has made the valuable glass sculpture of the Carpathian dog disappear, and who is trying to make it impossible for all the tenants to stay in the large apartment building? The few clues point in different directions, and once again, our detective trio has a tough nut to crack. Will they bring light into the darkness?.
