I take my hat off to the 'paper-and-pencil practitioner' Peter Newby for his clever article "Opera's Not Over 'Til Arepo Returns", which I naturally assume was produced without the aid of a computer. At first sight I thought he really had beaten computer buffs to the punch. A few weeks ago I tackled this classic problem, using the Wordsworth database of 14,300 five-letter words; I gave it up as impossible!
