This episode kept my attention because the suspect was not obvious at the beginning.
Kelly was undercover as a dancing girl for the production, Kris a reporter, and Julie was Kelly's agent.
At the beginning the suspicious person was the janitor boy, then it was possibly the choreographer. However, the Angels dug deeper and started to look at Darien Mason.
Darien was actually hiring poor dancer so they would not get the production. Darien already had several investors and if it failed he would walk away with the invested amount.
Great action at the end when Kris dives out of the way and Julie and Kelly stop Darien at gunpoint.
