Raymond Briggs, the writer and illustrator who died on Tuesday, created many memorable characters but none as haunting as Jim and Hilda Bloggs, the elderly couple enduring a nuclear attack in When the Wind Blows.
As news of Briggs’s death circulated, social media filled with people of a certain age recalling childhood nightmares derived from the poignant attempts of the Bloggs to follow the absurd instructions from a civil defence pamphlet.
