Sally-Anne Tapia-Bowes has written her 3rd thriller, it is stunning, dark and twisty and delicious. Focussing on two background characters from her other two Southport books, but boy, do they come to life in this one. Partly told in flashbacks and partly in the tense and murderous present. Her trilogy is sequential in time, but any of the 3 books is perfect on it's own.
