Melchbourne's dam, False Evidence, was of no use as a racehorse, failing to win in fifteen starts on the flat and four over hurdles but was a successful broodmare, going on to produce Cry of Truth.
Miss Lawson Johnston, a Master of Foxhounds and Justice of the peace, sent her filly into training with Bruce Hobbs at the Palace House stable in Newmarket, Suffolk.
She recorded her first victory with a three length win in the five furlong Little John Maiden Stakes at Nottingham Racecourse and followed up by easily defeating twenty-three opponents in the Quickly Plate at Windsor.
In September the filly was brought back in distance to five furlongs and started 11/4 favourite (after heavy support in the betting market) for the Harry Rosebery Challenge Trophy at Ayr Racecourse.
In the British Free Handicap, Melchbourne was allotted a weight of 120 pounds, making her the equal-best two-year-old filly of the season, alongside Bitty Girl and Gentle Thoughts.
