I really enjoyed her debut, Into the Darkest Corner, but didn't think much of Revenge of the Tide. So I approached HR with caution, but I thought it was a return to form. Found both Annabel and Colin interesting, well-rounded and believable. And I really bought into the format, especially the victims briefly telling the story of their deaths. The whole theme of loneliness and aloneness was very poignant.
The only reservation I have was the comparatively "easy" resolution and the climax that felt rushed and insufficiently tense.
Funnily enough the whole idea of a sociopath simply talking to his victims and them then killing themselves put me in mind of the pilot episode of Gatiss/Moffat's Sherlock, as that's what their killer says he does. But this book takes that idea and develops it in a different (more chilling) way. I'll be wary of strangers tapping me on the arm in future
