A Hobart merchant's night of adventure when fireman on a Tasmanian railway line in 1871. Three escaped ticket-of-leave convicts, brigands at large, capture the engine he had prepared for a new trip from Launceston and - one of them recognising him as a witness who had helped convict him - he is suspended between the front buffers of the engine and endures a nightmare ride expecting death at any moment ... Well-paced narrative of action and terror in a Tasmania still in process of settlement. Includes a degree of intellectual reflection. (PB)
