The distant echo

From McDermid's webpage: "Four in the morning, mid-December, and snow is smothering St Andrews. Student Alex Gilbey and his three best friends are staggering home from a party when they stumble upon the body of a young woman. Rosie Duff has been raped, stabbed and left for dead in the ancient Pictish cemetery. And the only suspects are the four young students stained with her blood.

Twenty-five years later, Fife police mount a cold case review. Among the unsolved murders they’re examining is that of Rosie Duff. But someone else has their own idea of how justice should be done. One of the original quartet dies in a suspicious house fire. Soon after, a second is killed in what looks like a burglary gone sour. But Alex fears the worst. Someone is taking revenge for Rosie Duff. He has to find out who it is before he becomes the next victim. And it might just save his life if he can uncover who really killed Rosie all those years ago."
