From Acorn TV:

Inspired the beloved characters created by Jill McGown, former lovers and detectives, Chief Inspector Danny Lloyd (Philip Glenister, The Level, Outcast) and Inspector Judy Hill (Michelle Collins, Coronation Street) investigate the death of a 15-year-old schoolgirl found strangled and deserted in a public park.

From Acorn TV (exclusively British empire productions) you can stream this 1.5 hour British film which is not part of a TV series.

Although nothing special, the hour and half spent watching this detective story is not a waste. To tell you the truth, I suspected the real murderer from the beginning. But there is enough drama, including the personal crisis of an obsessive runner and his betrayal by his close friend, to make the story worthwhile.

Beats being depressed by 2018 USA politics.
