A well-written book that goes through a few peaks and troughs. An intelligent, but agoraphobic woman, is confined to her home and witnesses a crime. The book starts amazingly, centered on the woman’s life – that is both intriguing and informative. It dips mid-way when the crime gets committed, and the book becomes just another whodunit. It picks up again, three-fourths of the way, when our narrator is shown to be unreliable. But then dips again. The ending was disappointing. Neither satisfying not believable. What worked for me particularly was the writing – very today and now. Interestingly there were shades of ‘The Woman on the Train’ in the novel (It’s not just the title that is similar) – an incident only the narrator was witness to, poor credibility of the protagonist and so on.
