The Thames has frozen over forty times. A narrative snapshot from each of those events is captured in Helen Humphreys' work The Frozen Thames. On many occasions, the ice on the Thames gave birth to frost fairs, ad hoc gatherings of merchants, food vendors, gamblers and all manner of trade and cold commerce.

In 1684, a fox was set loose on the frozen Thames during a frost fair. Confused, it found itself lost in timeand space in a white and chilly London. It's been spotted in eight locations about the capital. Each location holds cryptic clues and ciphers which, when untangled, contains a piece of the final destination of the fox.

The Quest for the Ice Fox is a geographical mystery that requires its players to use their language, math and geographic gifts to discover the place in London, England, where a frightened fox, set loose for a hunt on the ice, is confused between the white world of the Thames and the snowy streets of London, and disappears into the city itself, appearing seven times and finally going to ground at its final, prize-winning destination.

Your task is to tackle each of the clues as they're revealed in a special Google Map, discover the final destination of the ice fox to keep it safe from its pursuers, and then enter our contest. If you are the first to enter with the correct location of the fox, you could win a $2000 travel voucher and a copy of The Frozen Thames by Helen Humphreys. The first five runners-up will win $100 worth of books from McClelland & Stewart and a copy of The Frozen Thames.
