A reluctant murderer--not her first plan--but when Phillip persists in being a pest. Ambrose, who we think of as reliable, is suspicious of her. The locked up laburnum seeds did it for me. A gardener wouldn't collect seeds of a plant she already has in Italy; she'd want something new. And we keep hearing repeatedly about her herbal tea and her skill with herbs. Yes, she saves Phillip. Yes, she decides to kill Phillip. Contradictory, but that's what makes the book intriguing. Points against the murder . . . She could have just let him die when he had meningitis. She returns the jewelry to the bank. Beginning and end . . . guilty men hang at the crossroads. Phillip throws a stone at the hanging man . . . is he throwing a stone at himself?
