I find this result very gelungen- especially the atmosphere at the beginning of the action. Peter and Justus are separated from each other, each with another person in an empty, windowless room and can not remember the last 24 hours. What About Bob, the listener does not experience first. Very successful, I find the reactions of Mitgefangen on Peter and Justus (Huh? What? You weigh determined a ton?) And especially the attached cliffhanger between the episodes Peter / Justus and later Bob / Jelena (although I found it a bit unfortunate that was at least not mentioned in a subordinate clause Who is Jelena. I've probably all the other consequences of her missed :-)). Whenever it gets exciting, the narrative position changes. This creates a similar voltage coil as the films "Saw" or "The Cube". Excellent! However, there is of me only four stars because in my opinion, was made nothing from the very very good start. The individual situation is resolved too quickly, as is the situation in which Peter is later. Even Bon has not really what to do. The tension disappears very quickly in a very strange resolution. Although the pace is never lost, but I like the end and the perpetrators overpass not (why again Justus?). That's why I give Wirde rather three stars the beginning actually five, of the solution. Come out on four. Still a worthwhile result with the three ???.
