Police whistle

Definition and stakes

Portrait of Barry Pain Barry Pain Stories in the Dark (1901)

A police-whistle screamed.
In front of the door of the house a black mass grew up, getting quickly bigger and bigger. It was a crowd of people swaying backwards and forwards, kept back by the police.
The police! He was discovered, then. He must get away at once, not wait another moment. Only the green light was looking at him.

In this neighbourhood, we are informed, it is etiquette to blow a police-whistle only when someone is being "done in."
We were also informed, in discreet whispers, that the "Guv'nor" of the Station "had it in for us." His grievance was this: that while a rival show across the river had been accorded a military picket by the War Office, he had been fobbed off with a mere guard of Special Constables. To date of writing his wrath still smoulders.
Our hours of duty are filled with dulness, but we live in hopes.
