Over at his Monster! blog, Neil Arnold tells the strange story of the Warrington Man-Beast, and begins thus:
"The town of Warrington, which sits on the banks of the River Mersey, is also a borough and unitary authority area of Cheshire. According to an obscure story from the 18th century, later repeated in Wally Barnes' 1990 book Ghosts, Mysteries & Legends of Old Warrington, a terrifying man-beast once stalked a farm in Warrington. One such farm, once known as Peggy Gronachs Chicken Farm harboured a bizarre story which Wally Barnes was told of in the 1940s. According to Barnes, Peggy Gronach was '...the most evil, ugly and haggard old wretch ever seen in the vicinity.'"
