Without Looking Back

I used to be called Louis Whittaker, he thought to himself. I had a sister called Millie and a brother called Max. I used to live in a big house in Paris. I used to speak French every day. None of this is true anymore...
Louis is a young Parisian with a lot on his plate - his parents are locked in a custody battle over him and his brother and sister, Mum is always working late and Dad is rarely allowed to visit. But his passion and talent for dancing and his friends at school mean that life in Paris is good and certainly not one he ever thought he'd be forced to leave behind. So when Dad suddenly whisks Louis and his siblings away on a surprise holiday to England, right in the middle of the school term, he isn't too thrilled, especially as Dad is acting strangely again. Why is he being so secretive and paranoid - could it be he has not fully recovered from his mental breakdown? The rented farmhouse in the Lake District is nice, but why is Dad furnishing it and why won't he let them call home? Then Louis comes across a poster - a missing person's poster. And it has his face on it...
