"How could I miss a chance to see my fave band, Lethal Injection, live? Even Bess wants in. But we're only going on one condition: If a case crops up, you'll leave it to one of the security guards. Just this once, Nancy? So we can actually listen to the music?"
"Where's the mystery in that?"
One rock concert. One big crime. Three of the best teen detectives of all time.
