Cover blurb
''A security force with no official identity... a managing director with no name... a sinister creature on guard patrol resembling some kind of hellhound... SeneNet is no ordinary multinational company...''

The Doctor arrives in Brighton, 1989, travelling alone. He soon discovers his old friend, the Brigadier, has gone missing investigating SeneNet, whose new interactive games console is soon to be released at an absurdly reasonable price. He was last seen at their headquarters — based in the picturesque Ashdown Forest...

Investigating further, the Doctor becomes more and more entangled in a deadly web of intrigue. Together with Mel, a plucky computer programmer from Pease Pottage, the Doctor must overcome the conspiracty of silence, rescue the Brigadier and save the world once again — something that would be a lot easier if he just know where to start...

Featuring the Sixth Doctor and Mel, this adveture takes place between The Trial of a Time Lord and Time and the Rani.
