The gripping, twisty page-turner you wont be able to put down this Christmas
Last night my sister was murdered. The police think I killed her.
I was there. I watched the knife go in. I saw the man who did it.
And heard him laugh because he knows he'll never get caught.
He knows I have prosopagnosia - I can't recognise faces.
And if I don't find the man who killed my sister, I'll be found guilty of murder.
