Match-fixing in Regency cricket was almost as old as betting on the game. The big stakes attached to MCC matches — sometimes a thousand guineas or more — drew gamblers, jockeys and tipsters; corrupt arrangements between players were widely suspected and occasionally proven. The 1817 England v Nottingham match, played at Trent Bridge or possibly at Nottingham racecourse (sources differ on venue), was widely reported as a 'cross' — a match in which both sides agreed to lose. Lambert played for England. Whether he had actually conspired to lose, or had merely underperformed in a single innings, was never publicly established. The accusation was framed by Beauclerk, who had been collecting evidence on Lambert for years and used the inquiry as the means to eliminate his most dangerous professional rival from senior cricket. The MCC committee, dominated by Beauclerk and his allies, met in late July 1817 and resolved that Lambert was 'no longer to be employed at Lord's'. There was no formal hearing in the modern sense. Lambert had no opportunity to confront witnesses. The MCC's authority did not extend to other grounds, but in practice Lord's controlled the senior fixture list, and a Lord's ban meant the end of senior cricket. Lambert was 38. He returned to Reigate, took up tavern-keeping, and continued to play country-house cricket for another twenty years. His last recorded match was in 1839, at the age of 60.
