Summary:

Waiting for the Eurostar in Paris, Mark’s four-year-old daughter alerts him to a ‘Bad Man’ during a game of ‘Eye Spy’.

Things only get worse when Mark notices that the man is on their train with a suspicious-looking suitcase, and he’s sitting ominously close.

With secrets unravelling from the past, can Mark piece together the jigsaw of his life in order to save his family?

Or will their journey come to a fatal end?

Review:

Eye Spy is such an engaging and addictive read which absolutely tears along at a fast and furious pace! It’s not a short book, yet I read it pretty much in one sitting, and thoroughly enjoyed it. It’s a brilliant example of how intense a locked room (or rather, locked train) thriller can be, where everything feels like it’s happening in real time and you have no idea where things are going to end up for these characters. I loved the whole concept of Mark’s young daughter pointing out a ‘bad man’ during a game of eye spy whilst waiting to board the Eurostar from Paris to London and things escalating into a full on urgent and twisted race against time to save his family and solve a mystery from his past. The action pretty much focuses on the events on the train with some brief interludes of Mark’s wife, back in London, in a tense and mysterious situation of her own. The present events also relate back to a tragic incident six years earlier which is still having an impact on Mark especially, and everything ties together perfectly in a satisfyingly dramatic crescendo which had me completely gripped until the end. C. M. Ewan does a fantastic job creating a tension-filled and incredibly propulsive thriller that you will be unable to put down from beginning to end. If you like your thrillers high-pressure and full of intense twists and turns then I highly recommend adding Eye Spy to your TBR.
