Ep 13. The Case of the Borrowed Brunette

Melvin Slater is interviewing candidates to impersonate a woman named Helen Reynolds for some unknown reason. Eva Martell is chosen and moves into a nice apartment with her aunt. They are paid well by Slater as long as Eva continues her impersonation. Smelling a rat, Eva goes to Perry Mason for advice but she soon needs more than advice when Slater is found murdered in the apartment.
