A Shot in the Dark (2018)

After the notorious 'Middle Street Massacre' of 1951, when the majority of Brighton's criminals wiped one another out in a vicious battle as the local police force enjoyed a brief stop en route for an ice cream, Inspector Steine rather enjoys life as a policeman. No criminals, no crime, no stress. He just wishes Sergeant Brunswick would stop insisting that perhaps not every criminal was wiped out that fateful day.

So it's really rather annoying when an ambitious — not to mention irritating — new Constable shows up to work and starts investigating a series of burglaries. And it's even more annoying when, after Constable Twitten is despatched to the theatre for the night, he sits next to a vicious theatre critic who is promptly shot dead part way through the opening night of a new play.
