'My husband, Colin Macdonald, and I were introduced to Luise Hercus in 1990 by our mutual friend Isabel McBryde, a gifted talent scout, who realised how much our interests might overlap: Luise was doing fascinating fieldwork in South Australia, and Colin and myself were a retired couple with a diesel four-wheel drive and a love of exploring the countryside. As a result, we accompanied Luise on twelve of her field trips between May 1991 and September 2000.' (Introduction)
