When her mom calls to tell her that Tess, her younger sister, is missing, Bee returns home to London on the first flight. She expects to find Tess and give her the usual lecture, the bossy big sister scolding her flighty baby sister for taking off without letting anyone know her plans. Tess has always been a free spirit, an artist who takes risks, while conservative Bee couldn’t be more different. Bee is used to watching out for her wayward sibling and is fiercely protective of Tess (and has always been a little stern about her antics). But then Tess is found dead, apparently by her own hand.
