Araucaria: 'He never dumbed down'
"Until right at the end his mind was active. His final puzzle for the paper, published on 16 November 2013, was up to the standards of his very best. One clue (15 down) was a classic Araucaria mixture of current political and personal concerns. "Swap large numbers in protest from Lincolnshire town: no wind farm!" links nimby protests against renewable energy sources with the town of Louth, which he always wanted to visit and now never will. NIMBY LOUTH (swapping M/1000 for L/50) became NIL BY MOUTH to someone with cancer of the oesophagus in a Cambridge hospital."
