Val McDermid's The Distant Echo is, even more so than with her previous work, a masterpiece of trickery and misdirection. In 1978, four male students find the body of Rosie Duff half-buried in the snow and their lives are variously damaged by the suspicion that falls on them when the murder is never solved; a quarter of a century later, the case is reopened and suddenly the quartet start to be killed one after the other.
