Patricia was 47, a teacher at the local convent who already had two children of her own and fostered a third, Christopher's big sister Michelle. If adopting Christopher was a duty, it was one the couple carried out as wholeheartedly as their age allowed. It was a fairly solitary life. Christopher was adored, particularly by his brother William, who was eight years older. But the siblings were all much older, and away at school, and it would have been hard for strong links to develop between them.
