It does seem to have most of the elements you mentioned:

Martin confounds police procedure by changing what the narrator calls his "modus operandi," transforming himself from a burglar to a robber. In his new incarnation, Martin terrorizes the city with a series of daring liquor store robberies. The man's intimate knowledge of how the police work suggests that he is a rogue cop. His cunning duplicity revealed by police lab work (bullets fired from the cop killer's gun are shown to match one fired from the robber's), the killer is eventually, in a striking sequence, given a face by police artists, who assemble the robbery victims to construct a group portrait. The patient and time-consuming check of leads provides yet another breakthrough. Martin is identified by Brennan, who wearily troops from one area police station to another looking for a match to the composite sketch. Surrounded a second time, however, the resourceful Martin manages to escape the police cordon into his sewer hideout. There he can only be stopped by his own bad luck (the blocked manhole cover) and the heroicbut groupaction of the police.
The unfortunate criminal is gunned down in a shootout reminiscent of the western and the classic gangster film (such as Public Enemy [William Wellman, 1931], High Sierra [Raoul Walsh, 1941], or White Heat [Walsh, 1949]). This climactic sequence provides Martin with a dramatic apotheosis, as his bullet-ridden body tumbles from a ladder into the sewage below; he suffers a literal fall from power and control. Significantly, there is no closing narration to fix the meaning of this event, no celebration of the successful pursuit of a dangerous felon. The law triumphs, but that victory is not documented; it is neither brought into the public realm to be adjudicated nor stylized as real. The surveilling and enforcement powers of the police may prove superior (if only barely) to Martin's monstrousness, but in the clash of representational traditions the expressionism of film noir, and not the naturalism of classic documentary, furnishes the film with its summa-tive image.
As does the noir semi-documentary more generally, He Walked by Night juxtaposes a city of light (populated by citizens going about their business and surveilled by the benevolent police) and a city of darkness (a criminal underworld that, metaphorized by the darkness and night that enfold it, does not easily admit the knowing, official gaze). Like the film's narrative and visual structure, the sound track is schizophrenic, split between the heavy, grim romantic theme that plays over Martin lurking in the shadows and the upbeat, almost military air that accompanies the work of the police, the grinding routine according to the book, which eventually identifies the criminal.
