Unfortunately, a very weak result. It starts very promising and is reminiscent of the one or the other psychological thriller such as SAW. However, it lacks the "Psycho". The protagonists never have real panic or are short sane as otherwise very happy doing as Peter. Here in my opinion the most potential was wasted. Relatively early in the radio drama arises the question whether one or another inmate has something to do with the matter. But the figures remain an unknown quantity, and a suspicion is forgotten after only one minute. In addition, the passenger is left too little space. Instead, determine Elena and Bob where her, or at least stop Bobs friends. But this search bothers more and throws a out of the already overly exciting prison scene out. Moreover, their investigation for the resolution of the case are practically irrelevant. The apparently weak end will be replaced by an even weaker and überzogeneres, yes brain cracked end having some logic quirks. Who would not know the three question marks, this result should not be used to get to know. I recommend rather the result: "Double Deception". The result is exciting, has no pale Charaktäre and a good story. This should be the answers to the three questions (sign).
