The Rock. 1966.
A beautiful woman lies dead, a knife through her heart. 
 
The Rock. Present day.
A failure in judgement has cost DS Tamara Sullivan dear. Exiled to Gibraltar for a three-month secondment from London's Met, she feels she's being punished – no matter how sun-kissed the Rock is. 
 
But this is no sleepy siesta of a posting. Paired with her new boss, DCI Gus Broderick, Sullivan will need all her skills to survive the most dangerous case of her career.
A young constable is found hanging in his apartment. With no time for introductions, Sullivan and Broderick, unravel a dark and sinister secret that has remained buried for decades. 
 
Are they prepared to face the fury of what they are about to uncover?
