Every summer holiday I’d lay awake on the narrow bed and listen to the only other piece of furniture in the room – the hulking wardrobe, as the beetles dined. This was the nightly ritual at my grandparents’ cottage, where the insects would feast en masse during the dark, tapping their mandibles loud against the wood till they finally stilled, replete at dawn. It was the closest I came not to adolescent rage but to adolescent madness: whipping from my bed, torching the light and poring, murderously over the bedroom furniture for something, anything to obliterate under thumb.
