Just as if a fox had got into the hen-house in the dead of night, the 1,000 Guineas betting market was all of a-flutter early yesterday. For more than two hours, starting just before five o’clock, the price of the hot favourite Rainbow View began, mysteriously, to lengthen on the online exchange Betfair, eventually trading at 9-1. Slightly headlessly, some of the conventional firms temporarily suspended trading after they picked up the drift, sometimes an indication that all may not be well.
