The Organisation has despatched Ishmael and his partner Penny to Coronach House on the shores of Loch Ness where the secretive but highly influential Baphamet Group are holding their annual meeting. The Organisation believes an imposter has infiltrated the Group and they have instructed Ishmael to root him - or her - out. It's not Ishmael's only mission. The first agent sent by the Organisation has been found dead in her room, murdered in a horribly gruesome manner. Ishmael must also discover who killed his fellow agent, Jennifer Rifkin - and why.

Dismissive of rumours that the legendary 'Coronach Creature' is behind Jennifer's death, Ishmael sets out to expose the human killer in their midst. But he must act fast - before any more Very Important People are killed.
