It's Dark Outside(1964)

It's Dark Outside is a British crime series that spins off from The Odd Man, following the sharp-tongued Inspector Rose as he navigates murder investigations alongside Det. Sgt. Swift, a more sensitive counterpart. The first season brings in Anthony Brand, a barrister, and his wife Alice, a journalist, who become entangled in the cases. By season two, the ensemble shifts dramatically. Swift and the Brands exit, leaving Rose as the show's cold, methodical centre. He's joined by the ambitious DS Hunter, his girlfriend Claire, and Fred Blaine, a hard-drinking reporter with his own agenda. The dynamic between Rose's icy professionalism and his new team's messier personal lives drives the darker, grittier tone. It's Dark Outside balances procedural mystery with character study, exploring how ambition, romance, and addiction complicate detective work.
