From The Perry Mason TV Show Book
Columnist and socialite Mary K. Davis gets herself killed. Was it her shrill voice that prompted someone to do her in? Or was it something the columnist said? Maybe her politician-husband didnít appreciate her refusal to give him a divorce. Or perhaps that doctor didnít like it when Mary threatened to expose his illegal baby-selling scheme.

Perry and Della feel itís an important enough issue to tamper with the evidence in defense of Leona Walsh, the nurse on trial for the crime. Burgerís out to put Della on the stand and get Perry for tampering.
