The Arnelo Affair is a 1947 American film noir starring John Hodiak, George Murphy, Frances Gifford, and Dean Stockwell, and co-written and directed by Arch Oboler.

When Tony is made to realize that his lies and blackmail will destroy innocent Anne's place in society, he escapes the detective's custody in order to commit "suicide by cop".

The staff wrote, "Arch Oboler, radio’s master of suspense, has effectively transposed his technique into the visual medium with The Arnelo Affair.

Strictly speaking this is not a whodunit, nor can it be catalogued as a psychological suspense picture ... There’s never a question as to who committed the murder, but the crime is secondary to its effect on the characters involved.

Dialogue instills the feeling of action where none exists for much of the footage, and the gab is excellent but for a couple of spots when Oboler gives vent to florid passages.
