The night mayor - Kim Newman

In the City, it's always two-thirty in the morning and raining. Edward G. Robinson is strangling Joan Bennett on a fire escape, James Cagney is bleeding to death in a gutter, Humphrey Bogart is walking the mean streets and the Night Mayor has the power to assume any identity he chooses. The City is the dream refuge of Truro Daine, alias the Night Mayor, the twenty-first century's Napoleon of crime. The Gunmint can't let Daine escape, even it's only into his own imaginings. Against the film noir landscape, Dreamers of genius Tom Tunney and Susan Bishopric must pin the Night Mayor down before his dreams of re-entering their world become deadly reality.
