Here we go, as it's so often gone off, the three question marks are in their headquarters in the junkyard. Suddenly an acquaintance of them emerges, who reports to you by the new Disco Planet Evil. There lie every night at midnight the DJ Devil, also called Satan Dj on. He would act almost hypnotic to the audience, they like to draw invisible threads. It should also be a classmate, after they had let themselves lenekn of the DJ, collapsed unconscious. Just, Peter and Bob obviously want the thing to track down and get the next night, as it should be otherwise, Duch to this strange DJ to take the toilet window in the disco one they are buying. Also that night enters the sondebare DJ at the turntables and in fact he has no head! (If you have not entirely turned off the mind is an immediately apparent that he has been hiding him only under the costume). And of course, it also comes in the night to a "accident", as directed by threads punched an elderly woman to ecstasy until it falls down and is dead. Suddenly, the DJ has disappeared. At least now the determining impulse is awakened in the Three Investigators. This is followed by investigations, abstruse explanations are found, such as that in the musical sounds are woven, the trigger in the audience happiness state. Until it comes to an end in a very parlous state resolution of the case. At least the three detectives remain quite faithful, Justus combined still lightning fast and has the result always, Peter is in front of his colleagues and is athletic, but also the most timid of the three, well and Bob, Bob is just responsible for the archive. Is completely unnecessary that a storyline is woven, which must, of course, come with a raised index finger when it comes to nightclubs: The vexed question of drugs. And Peter gets offered Ecstasy and short log it so that he takes it, but of course comes out later that he did not take it, how could he otherwise remain our sporting idol? The border is just asking for educational instruction. Totaly, the story drags down so voltage will not rise properly, but maybe that's a good thing, after all are just three ??? Cassettes of many commonly used as a sleep aid.
