For me, Michael Robotham's thrillers remain essential reading that demand some booking of 'time out' from normal life. And so it came to pass that his latest, his fourth novel in this series, Shatter did exactly that. I could have read this in one sitting, but one or two or more sittings had to suffice - due to some essential house moving - it all had to be done, including the reading of this novel.
Within a troupe of characters, Robotham kicks and slides the focus for his main protagonist like legs in an Argentine tango. This, in part, provides the beauty of the series as you never know what's coming next. Now, with book four, we return to book one: psychologist Joe O'Loughlin is the protagonist, but still with room for Vincent Ruiz (now retired).
