Thanks, Christina; I wondered if anybody else was thinking along these
lines.
The book was fifty years old, so it could easily have been mom's or
Slughorn's, complete with margin doodles. Slughorn likes to adopt
students of promise, hoping to share their future limelight, so I
could easily envision him loaning the book to Snape, and later to Harry.
That would explain why nobody else came across it during those twenty
years when Slughorn was away.
