The processing of the result has certainly advantages and disadvantages to offer. Definitely a shame is the fact that the warning to the three friends, a fire in the outdoor workshop in the junkyard, has found in radio play no place, because this would have been well worth some playing time.
Instead, a long (and partly unnecessary) dramatic introduction is presented in art class, where the two slobs Wayne Dillion and are placed in the focus, even though they are not in the radio play continued relevance.
So falls on once again that the storylines from the book will not be reduced consistently enough. Some passages thus do not fit into the story being told or can be understood only on the edge, virtually when the book was read previously.
Technically, the production is at a reasonable level, although now repeat designed by STIL team music elements from the previous cases slowly. Stark is the cast's performance. In addition to the three detectives a very strong acting Tilo Schmitz helps that the appropriate mood is also transferred. The performances by Klaus Dittmann and Jürgen Thormann have it in them.
In short: "Black Sun" has been well implemented and provides for a term of just over an hour for a reasonable and straightforward conversation, even if the end of, unscrupulous se antagonist, acts a little odd - just exactly as in the original.
