When We Were Killers

Five friends. One deadly obsession.

WATERSTONES SCOTTISH BOOK OF THE MONTH - MAY 2025. The salt-scented quadrangles of St Andrews University greet misfit first-year student Finn Nethercott with indifference. It is a place where privilege counts, and those from the right backgrounds can get away with murder.

Finn is quickly seduced into a new circle of friends – four history scholars obsessed with the deepest roots of ancient Scotland – who sweep him away on wild adventures to forgotten castles and faerie lochs.

But he soon discovers the darker sides of his new deadly rivalries, midnight rituals, and a desperate search for a long-lost hallucinogen. And as Finn sinks into a world where he can't always trust what he's seen each night, the group will learn just how deadly obsession can be…
