I Used To Watch This?

A popular radio DJ is killed while live on air and David thinks it's a great case for the Blue Moon Detective Agency. Maddie is resistant at first, but then decides to go along with it after she listens to some recordings of the show. But, then the DJ turns out to be alive! Then someone else is killed and it has to be someone associated with the DJ. It's a little confusing, but a lot of fun!
