The Murder Rule

Dervla McTiernan

HarperCollins £14.99 Lawyer-turned-writer McTiernan sets her latest thriller in the

US, rather than in her native

Ireland. Law student Hannah

Rokeby is ruthlessly fixated on becoming part of an Innocence Project crusade to free convicted rapist and murderer Michael Dandridge. It soon becomes clear that her true motivation is to sabotage the campaign rather than to help it. But why? This is a thoroughly engrossing mystery, let down a little by a credibility-straining courtroom finale.
