He married an older woman who had money.
Killing her was his way of being free and rich.
Like Richard Kiley in " A friend in Deed".
He used the girl, he didn't love her.
His confession didn't work imho.
The play has a different emphasis ( i own a copy).
It's more about the psychiatrist who truly does love the girl .
Gene Barry played him as a cold, calculating killer.
I'm curious to see the tv version.
Thanks for the info!

I just watched ENOUGH ROPE which has a completely different ending from the stage play and PRESCRIPTION MURDER even though it is credited to Levinson and Link!
Is there ANOTHER tv play with the phony suicide/ confession ending?

Btw Bert Freed was totally wrong for COLUMBO ( although, like Falk he wears a bad toupee!😉).
It makes you really appreciate the genius of Falks interpretation!
