Actually, Justus, Peter and Bob should convert a car to its new owner, however, come here at night in a thick fog, which forces them to stay at a hotel. And here the whole horror begins. The hotel is run down and seemingly abandoned, the sudden appearance owner turns out to be strangely expressed. When he confronted the 3 question mark with a riddle that will lead to a treasure that has been missing for a mysterious plane crash about 10 years ago, Justus, Peter and Bob are in the middle in a new case, which has it all.
The tension is built up at the beginning of the story (which is also a wonderful background music contributes), is maintained until the end, because nothing is as it seems. The one or other unforeseen turn is thus inevitable. In the resolution of the case, the three fall into some dangerous situations and the abandoned puzzle has a really imaginative solution, to which the audience can look forward.
I especially liked about this episode that the characters are this time very lovingly designed. The peculiarities of the detectives, such as anxiety Peters, the fate of Bob and the constant appetite Justus are nicely incorporated and lead to a nice pun and small frictions between the three, which I like personally. Also raises Justus again some technical terms in the room, becoming its reputation as a walking encyclopedia justice.
The peculiarities of the hotel owner is even a small nod to "The Lord of the Rings" installed, which I find quite succeeded.
A small deduction there, because the end is indeed reasonably credible, but bit far-fetched in my eyes.
Overall, I would highly recommend this series but and all those who just love the nice subliminal humor between Peter, Justus and Bob as I will come in this sequence at their expense. Enjoy listening and tenterhooks!
