Erica is a crime writer and married to Patrick, a detective. While looking though some old items of her mother, she comes across a Nazi medal. Erica is shocked and needs to find out where and who this medal belongs to.

Erica search leads her to a history teacher who was one of her mother's friends during the war. Two days later he is dead. Patrick is assigned the case. Patrick was on paternity leave, but he accepts this assignment. Why would someone go to all this trouble to kill someone all these years later?

I hate to say it, but I just couldn't wait to finish THE HIDDEN CHILD. Not because it was so good, but because for me it was way too long at 400 pages. I am sure that there are people who enjoy Camilla Lackberg's books, but I had to put THE HIDDEN CHILD down several times to read another book. I did keep going back, because I was hoping it would get better. I am by no means trying to discourage any one from reading THE HIDDEN CHILD, but it just was not my kind of mystery book.
