Tomorrow at Seven is a 1933 American pre-Code mystery comedy film directed by Ray Enright and written by Ralph Spence.

The plot sees a group of people gathered in an old mansion being menaced by a killer known as "The Black Ace".

The killer sends his victims a Black Ace card, warning them they are to die and then kills them, his way of taunting the police.

Neil Broderick, an author, intends writing a book about him and is on his way to see Thornton Drake to get more information about him.

Neil goes to Martha's room and asks her what she did with the letter, guessing that she had taken it because was afraid her father might implicate himself with the Black Ace.

Downstairs, Dugan has been talking to Martha with his back to her, turns and sees she has gone (a mysterious hand reached out for her only moments before).

The housekeeper (Mrs Quincy) is seen leading the fake coroner (Jerry Simons) who is carrying Martha.
