You can't insure against bad neighbours, but they can blight your home and peace-of-mind much more disastrously than a combination of mere dry rot and a leaky roof. A burning feud may be sparked by no more than a cup of sugar - never replaced - borrowed 19 years ago. Or early morning lawn mowing. Or the same piece of music played too often and too loudly. Nerves tighten, tempers flare. Threats, retaliations, even the law can follow. Neighbours have wound up in prison. Jeanne La Chard looks at these neighbourly wars - often amusing to outsiders, never so to the participants - and asks what, if anything, can be done to solve them.
