While on holiday in Scotland, visiting a macabre tourist
attraction, 'The Dungeons of Edinburgh', a young Russian tourist is
murdered. As the police grapples with the fact that the cause of
the young man's death was a massive loss of blood, the Watches are
immediately aware that there is a renegade vampire on the loose.
Anton - the hero of The Night Watch and The Day Watch - is detailed
to this seemingly mundane investigation, but on arriving in
Scotland begins to realise that there is much more to the story
than a wildcat vampire and a single murder. Aided by Thomas, the
head of Edinburgh's Night Watch, Anton investigates and ruminates,
and becomes aware that a team of unlicensed Others are hunting for
a fabled magical treasure, hidden in the sixth level of the
Twilight by Merlin himself.
