A deadly secret whispered by a dying gunrunner on a lonely road in Zambia sets MI6 agent Sam Packer on a frantic race against time. A terrorist gang has acquired a horror weapon but before Packer can discover more, the man dies. Packer is on his own, faced with sceptical colleagues and
the gunrunner's daughter Julie, who may hold the key to the secret but who also suspects it was Packer who engineered her father's death. Betrayed and compromised, Packer follows a faint trail of coincidences that began with his own father's disgrace twenty-seven years before. As Packer fights desperately to win Julie's confidence, the unlikely pair follow the trail of murder and deceit from Scotland to Vienna and on to a lonely island in the Adriatic: there they will find not only the weapon but the identity of the sinister organisation known as the Lucifer Network.
