#1 international bestseller
"Brilliant!" - SUNDAY TIMES

He sneaks up behind you in the crowd every day. Now he knows your name.

Zoe Walker spots her own photo in the classifieds section of a London newspaper. No explanation: just a grainy photo, a website address and a phone number. Zoe shows the newspaper to her family, who are convinced that the woman in the picture just looks like her. The next day, however, another photo appears in the newspaper, of a different woman, and then again the next day of another. Zoe watches the news suspiciously and soon finds a connection between the images: the women were victims of a crime.

Zoe's paranoia grows. Did something go wrong? Coincidence? Or is someone doing what the signs suggest: following every move of the women in the pictures with a prying eye?

Clare Mackintosh's #1 Sunday Times bestseller is a nightmarish yet brilliant psychological thriller in which the author strips away our fears and invites us to play dangerous games.
