FOR AS long as I can remember, and that's about 16 years, Jean-Paul Maigres the travelling fishmonger has been turning up in the village in the early evening. Around 6pm the giga-decibel loudspeaker attached to his van announces his arrival, and because the village is cradled in a steep-to valley the sound carries everywhere and there's no mistaking, if you were in any doubt, that it's either Wednesday or Friday, the two days on which he trawls for customers round the village streets.
