Even with the cheesy singing and the poor acting by a so-called British pop star, the mystery was good enough to uphold the entertainment value of a 'Perry Mason' episode. If you can by-pass the singing and concentrate on the adults interactions then this episode is really not as bad as some have suggest.
The story centers around a young British singer named Sandy Chester. For some reason a wealthy man, Cameron Burgess, calls Perry Mason and wants to financially support the young Sandy in trying to get started in the music profession. Burgess get Mason to hire a rough cad of an agent named Clete Hawley. Hawley is the type of guy that would sell his mother's house right out from under her if the money was right.
Hawley does do some good things for Sandy until he starts control everything in his life. When Hawley finds out who is financially backing the singer, he naturally sees dollar signs in his eyes. But with nearly everyone disliking Hawley, there is a cast full of suspects when they find Hawley dead from being stabbed by a pair of scissors. But the person found in the dead man's room is none other than Sandy Chester. Perry will defend the young singer in court for the charge of murder.
There is a lot going on in this episode. Facts about the early years of Sandy's life is revealed- the way Hawley treated his employees are revealed- plus secrets are explained. It all comes down to Perry's courtroom examination that the true murderer is found. Try to by-pass the singing and this is not a bad mystery.
