Amid the riot of rainbow stripes, Sister Joan Doyle and her colleague, Sister Patricia McDermott, white-haired, 60-something Sisters of Mercy, are dressed down for the dust in Lima, in T-shirts and jeans. In 1996 they set up a women's centre, the childcare centre and the health clinic they set up in a poor community on the outskirts of the Peruvian capital. Now they are leaving for poorer pastures, reports The Sunday Age.
