A notebook full of secrets, two untimely deaths - something sinister is stirring in the perfect seaside town of Morannez…

It's summer and holidaymakers are flocking to the idyllic Brittany coast. But when first an old traveller woman dies in suspicious circumstances, and then a campaign of hate seemingly drives another victim to take his own life, events take a very dark turn.
