The book started fabulously with an old faded envelop found by the cat sticking out of the floorboards in the kitchen. The doors were closed, how did the envelop get there? Lizzy was shocked and fearful. And the story continued on with her getting more such messages about someone keeping a watch on her. This continuous feel of threat made her paranoid, and everyone was a suspect. The story unfolded till the last page.
I have been reading this author's work religiously for the last three books, and though this was a good book with twists and turns, for me it didn't have the bang except for the epilogue. That was unexpected!!
The story was well paced, had Lizzy in a tizzy sometimes very dizzy, always busy with fear. The feeling of being watched kept a hold on the story. I liked how every character behaved suspiciously after the onset of these letters. The doubting facet of a scared human nature was well written.
Lizzy was likeable in some ways, didn't like her boyfriend Joe, I felt she could do better than him. On the whole, she was not a strong main character. Joe was a horrible boyfriend, controlling and suspicious. She spent 5 years or so with him, how? He even went to prison for violence. Why would any self-respecting, independent woman stay with such a man? The rest of the characters played their part, some of them were mere props.
