Traditionally!

"Blue Beast" recalls arg to the first episodes of the three detectives. Personally, I find the story rather weak, really do not want to skip the spark. The voltage very very very slowly built up, if it is then once there, it is also the same way again. I had this impression in many early episodes also.
[Spoiler] The solution to the blue beast calls a "For the whole trappings I would have expected more." out and leaves a bad taste. There appear people who will later never mentioned further, although one gets the impression that they would have the further course of the story well done.

On the speakers, there is still, as ever, nothing to complain about. The vile story was fortunately well-made, so the actual radio play pleasure nothing stands in the way.
For diehard fans therefore a pleasure for everyone else, it is sufficient for the way listening.
