Usually, if a Mr and Mrs are sitting down to a home cooked steak, and the baby girl is playing nearby, something may be afoot. The family is the unseen locus of much of film noir.
Here, Mr and Mrs Cop are seen at home perhaps a little too much; and its a signal that bad things are a-coming.
Although there are spoilers all across this website, a special SPOILER ALERT need be issued for Fritz Lang's 1953 noir, The Big Heat.
It isn't so much around the ending or the way things work out, its just that the likely most significant thing which takes this almost lackadaisical Langian noir out of the realms of the mere crime film en passant, is what happens at home, and the tragedy that befalls that home.
