A thousand cuts
(Book)

First published as Rupture by Picador, London, 2010.

It should be an open-and-shut case. Samuel Szajkowski, a recently hired history teacher, walked into a school assembly with a gun and murdered three students and a colleague before turning the weapon on himself. It was a tragedy that could not have been predicted. Szajkowski, it seems clear, was a psychopath beyond help. Yet as Detective Inspector Lucia May begins to piece together the testimonies of the various witnesses, an uglier and more complex picture emerges, calling into question the innocence of others. But no one, including Lucia's boss, is interested.--From publisher's description.
