Maxwell's Curse by M. J. Trow
Sixth baffling mystery in M J Trow's highly-acclaimed crime series featuring schoolteacher and amateur sleuth, Peter 'Mad Max' Maxwell. Peter Maxwell is about to celebrate the Millennium. Not the one everyone else celebrated - that was last year. His is the mathematically and historically correct version - 31 December 2000. But when the doorbell rings, it's no New Year reveller; it's the body of an old woman who, on a night of unseasonal mildness, has been frozen to death. The dead woman was Elizabeth Pride, who lives alone near Cisbury Ring, in the folds of the Sussex Weald. Rattled by the corpse on his own doorstep, Maxwell investigates and uncovers a sinister web of intrigue that focuses on a local Sports Club. At the dawn of the 21st century, Maxwell seems to have stumbled onto something every rational soul believed to be buried with the past: witchcraft.
