I just noticed this reference to domestic violence in Busman’s Honeymoon.
“"O-o-oh! I do hope he won't be violent."
"Violent?" said Harriet, half amused and half angry. "Oh, I shouldn't think so."
But alarm is infectious...and much-tried men have been known to vent their exasperation upon their[Pg 330] servants. The two women clung together, waiting for the explosion.
"Well," said the distant voice, "all I can say is, Bunter, don't let it happen again.... All right.... Good God, man, you needn't tell me that ...of course you didn't.... We'd better go and view the bodies."
The sounds died away, and the women breathed more freely. The dreadful menace of male violence lifted its shadow from the house”
Aren’t those last two sentences chilling?
