Fingers at the Window is a 1942 mystery film directed by Charles Lederer and released by Metro-Goldwyn-Mayer.

The police, led by Inspector Gallagher with psychiatrist Dr. Immelman consulting, arrested a different man for each crime, but all of them are impervious to interrogation, lost in a state of paranoid schizophrenia.

Later, someone in the shadows counsels a bird shop owner that he must kill dancer Edwina Brown and hands him an axe.

The shop owner gets in the window and attacks the dummy with the axe; they raise the alarm, and he is captured.

He eventually breaks in Dr. Immelman's file cabinet and looks under the "B"s. All seven men who did the axe murders are there, in order, as patients of another psychiatrist at the hospital, Dr. Santelle.

As he lies, bruised, in the hospital, Edwina reveals that she was engaged to someone named Cesar while living and dancing in Paris.

The police are convinced that Oliver is crazy until an officer spots the piece of paper Edwina got from the lunatic on the floor.
