The discovery of an arms cache bound for the IRA leads two agents to a terrifying cartel of arms dealers, the Mafia and international power-brokers all hellbent on destabilising the West. When the mission looks impossible, who do you call? UNACO.

When a schooner is wrecked off the coast of Nantucket, a group of children discover a treasure trove on the beach - brand-new Armalite assault rifles destined for the IRA.

UNACO agents Mike Graham and Sabrina Carver, their working relationship as volatile as ever, are pitched into the investigation and they soon find themselves tested to the limit in a web of intrigue that takes them from America to London, Switzerland and Ireland.

Arms, drugs, the Mafia and an international power game are at the centre of this complex and compelling story which moves at a cracking pace as time runs out for UNACO and the forces of peace.

Alistair MacLean's Dead Halt is the fifth novel to be written by Alastair MacNeill from a MacLean story outline. Readers will find this novel offers the same suspense and excitement as the bestsellers by the master storyteller himself.
