In Dresden Files book 3, Grave Peril, Harry and Michael Carpenter confront the ghost of Agatha Hagglethorn in the maternity ward of a hospital.
Agatha is in the process of murdering the newborns by suffocation. There is one specifically that she focuses on, shoving the stump of her arm into it's mouth to smother it.
The good guys win the day and save all the kids, and I distinctly recall Harry making note of the baby's name (though I don't have my copy at hand, so I can't look it up).
It seems strange to me that we would get a specific name for a child that isn't seen again. Similarly, it seems like such dramatic supernatural contact as a newborn could have lasting effects on the child.
Obviously, it will be years before the infant is old enough to impact Harry's stories again.
By book 14, Cold Days, years have passed. How many years have passed between book 3 and 14? Have we seen this child again? What was her name?
