When a teenage joyrider crashes a stolen car and ends up in a coma, a routine DNA test reveals a connection to an unsolved murder from twenty-two years before. Finding the answer to the cold case should be straightforward. But it's as twisted as the DNA helix itself. Meanwhile, Inspector Karen Pirie finds herself irresistibly drawn to another mystery that she has no business investigating, a mystery that has its roots in a terrorist bombing two decades ago. And again, she finds that nothing is as it seems. Sequel to "The skeleton road". 2016.
