“The Lumber-Room” by H.H. Monro (Saki) is one of the short stories from Beasts and Super-Beasts, published 1914, though it was first published in a newspaper. He died two years later in the war. Significantly for this short story, Saki was gay.
There’s something very Peter Rabbit about this short story for adults. Peter Rabbit was widely read to children at the time Saki’s story was published. It’s conceivable that the fictional adults in “The Lumber-Room” believed all children (as proxy rabbits) want to get up to mischief in gardens because they had read Beatrix Potter’s tale over and over.
