Status Updates From L'hora blava

Liking this book - the locale, storyline. Now feel a growing sense of doom for main character Becker. A string of people have died and the most obvious answer is Grace. Do I feel sympathy for her? VIndication? A little, now that more info has been revealed. Do I like Sebastian? No way, especially behavior with wife Helena, another barely likable person. As for Vanessa, we only know her from letters.
