I love Wilkie Collins’ gothic mysteries, and the title of this surely seems to deliver. But I was a bit dissatisfied with the ending and lack of explanation. Were the appearances and smells in the room just some kind of supernatural moral thing? I loved the gothic writing and Venice setting though. And I guess all got their comeuppance as Countess and Baron died, maybe Lord Mountbarry too as he had done the dirty on Agnes (though a harsh penalty, perhaps!), and a happy ending with Agnes and Henry marrying. Great plot device though, with switching identities of the dead person.
