The Spanish Uncle

Mary had looked after her little nephew Paul since he was a baby after his father, Enrique Alvarados had deserted her sister Sheila without marrying her, and Sheila herself had died soon after having the baby. But now Mary had met the child's imposing uncle, Enrique's brother Rafael, who had insisted that she bring Paul to Spain to meet his father's family and he soon made it clear that his idea was that Paul should live with them altogether. How could Mary give him up especially to the tender mercies of Isabel Ruiz who was almost certainly going to marry Rafael ? And was it just because of little Paul that she found the idea unbearable?
