Question about the house/set.....

When the story begins, Mrs. Marrable is talking to her lawyer in what appears to be a Victorian home: a lot of woodwork, pillars, mirrored mantel, etc. Was that supposed to be her house or the lawyers office?

The next thing you know, she's in Arizona murdering her housekeeper. The interiors of that house are completely different.

What did I miss?

Edited to Add:

I re-watched the beginning of the film again. The Victorian-appearing house was, indeed, Mrs. Marrable's.

But, I see no explanation as to why she's then immediately in an Arizona ranch-style home.

The acting in this film was good. But, I felt the direction from scene to scene was rather choppy and a little vague. It seemed a little cheesy. It looked really low-budget and didn't seem to have the production values of "Baby Jane."

(Robert Aldrich produced "Alice," but produced and directed "Jane.")
