Jurek Walter is thought to be back. Saga & Joona thought that he died when Saga shot him 3 times but the most vicious killer has returned & has captured Saga‘s father and sister and buried them alive. It is the 7th installment is the series by Lars Kepler and the best so far. All these books are very dark and violent but keep you on the edge until the very end. This one has a surprise ending and a cliffhanger and is no different than the others.
