Watson is a book fairy with Books on the Underground, a London-based group that puts about 150 books in the Underground a week for commuters to enjoy. Here she is, paying it forward last week in London:

She has also included notes:

Watson, though a British citizen, was hopeful for a Hillary Clinton victory; last month, she Tweeted, "In the last US election, 70 million women cast ballots versus 60 million men. Women, your vote could swing this election."
