Zoe Walker is riding the Underground home from work one day and perusing the local paper. As she skims the classified "adverts", she notices a small picture next to a dating website and has a feeling of familiarity with this photo...and then she realizes it's a photo of her. She is unsure as to how her photo is used advertising a dating website - she's happily married with two adult children, Katie and Justin.

Only after a woman is murdered does Zoe realize that she had seen this woman's photo a few weeks prior for the same dating website advert. She enlists the help of DC Kelly Swift.

Told in three points of view - the stalker, DC Kelly Swift and Zoe - the story unfolds with the police investigation into the dating website which would post a woman's commute route as well as a description of the woman and someone would pay money to follow her and abduct her.

Overall, a good book and story but a bit unrealistic at times. Good twist at the end. ( )

Mystery

Zoe is on the commuter train one evening when she happens across a photo in a classified ad, an ad listing a website known as FindTheOne.com. What is most surprising is that the photo is of herself, and she has no knowledge of how it got there or what it has to do with the website. A different woman's face appears in the ad each day, and soon Zoe realizes that several of these women have been recent victims of crime -- even of murder. After learning more about the website, she discovers that it's basically a tool to allow men to stalk women, esp. those who tend to follow a predictable routine day-to-day, and her initial worry turns into extreme paranoia.

I've heard that this thriller is not as good as Mackintosh's debut, but I found it intriguing and was rapt until the end. I was torn between conflicting emotions, one minute thinking this was too implausible but then the next I was doubting myself, thinking maybe in today's society this isn't so unbelievable. I will admit I was wrong about the whodunnit and it took me by surprise. There were lots of red herrings in this one, making me second guess myself a lot. Overall I enjoyed this one. ( )

Como cada día, Zoe regresa de trabajar en el metro de Londres. Sin embargo, al abrir el periódico, encontrará algo que perturbará su apacible vida. Un anuncio de la sección de clasificados lleva su foto. No hay explicación alguna: solamente la imagen granulada de Zoe, la dirección de una página web y un número de teléfono. Su familia está convencida de que el misterio no es tal, sino solamente un caso de extraordinario parecido físico. Pero, día tras días, en el anuncio aparece la foto de una mujer distinta... y su presencia en los clasificados parece ser el presagio de un mal que les ha de acontecer.
Zoe siente que alguien la observa, que alguien estudia cada uno de sus movimientos, y no cesará hasta descubrir quién se esconde tras las sombras. Pero el enigma quizá encierre un peligro al que no quiera enfrentarse.

Good, though I wasn't always convinced. ( )
