Alex Marwood might just be my new favorite author. I liked "Wicked Girls." "The Killer Next Door" is even better. A brilliant portrayal of urban life--with all its forgotten, discarded lives--coupled with a serial murderer that, as the title states, lives next door to the novel's 'inhabitants.' Brilliantly plotted. Brilliant character development. Brilliant narrator. I was riveted...and so incredibly disappointed when it came to an end. Highly recommend.
