The Last Vow

At a wedding in the Scottish town of Gretna Green, the bride collapses dead just seconds after the groom slips the wedding ring onto her finger. Someone has shot her. She is the seventeenth victim of an unknown attacker who has been terrorising the United Kingdom for the past few months. The scenario is always the same: one shot from a great distance, one unusually large bullet, one person dead on the spot.

No one knows how the sniper selects their targets or where they will strike next. Residents live in permanent fear, general panic grows, the economy suffers, and the police are clueless. That is why the proven trio returns to the scene: Washington Poe, Tilly Bradshaw, and Stephanie Flynn – the only team with a chance of tracking down a serial killer who has turned the entire country into his private hunting ground.

But how do you stand up to an invisible enemy who makes no mistakes and acts with no apparent motive? And what if the woman Poe cares about most in the world ends up in his crosshairs?
