Victor Kennedy's device

From Tardis Wiki, the free Doctor Who reference
Victor Kennedy's device. (WC: Tardisode 10)

Whilst sat in his office, Victor Kennedy used a handheld device in conjunction with his Vaio laptop to trace LINDA's location to Maccateer Street in London on Tuesday through their website, Who Is The Doctor?. Once activated, the device caused the laptop's display to read "PRIMITIVE COMPUTER PAGE" before displaying a map and text saying "TRACK SOURCE". The map closed in on Maccateer Street before the screen went blank, after which Victor absorbed his secretary. (PROSE: The Time Traveller's Almanac, WC: Tardisode 10)
