Tale about convict times, purportedly based on fact. The annual horse race in Sydney in 1806 is this time celebrating the news of Trafalgar and the arrival of two ships with provisions - one US, one British. A gawky horse belonging to an Irish farmer wins. The attendees include Governor King, Baron Ward, Mr Holt, Margaret Catchpole, George Barrington, and Kate Vaughan - a governess wrongfully convicted for stealing jewllery planted in her box by a jealous mistress. Tale is mainly of the plan to help her escape from Botany Bay on the Yankee ship: helped by the US Captain, the settlement's Dr and Mrs Laudus, and two gentlefolk from India. The gawky horse wins another race - this time to deliver a warning letter to the Yankee ship to depart before His Majesty's boat can reach and search her. (PB)
