Biography
During the 41st century, George Sheldrake crossed paths with the Nun. Though they got along at first, Sheldrake betrayed her and stole her TARDIS' temporal velocitar while sending her into the Time Vortex. (AUDIO: The Wrong Woman) Using Gallifreyan technology, Sheldrake developed the time tunnels, which he intended to release to the public as commercially available time travel. When the Space Security Service began investigating him, Sheldrake began using the time tunnels to foil their investigations, sending agents to assassinate witnesses. When Mark Seven began investigating him, Sheldrake arranged for his ship to crash on Mira.

On the eve of the time tunnels' public launch, Sheldrake was visited by a pastor, (AUDIO: Buying Time) in actuality the Nun in disguise, (AUDIO: The Wrong Woman) who he had thrown out, and also ignored the warnings of the SSS. (AUDIO: Buying Time) Sheldrake caught Anya Kingdom and the Nun when they infiltrated his base, witnessing the Nun's escape in her TARDIS. Unaware the Nun had reclaimed her velocitar, Sheldrake activated his public time tunnels on schedule causing a temporal cataclysm. After the disaster was stopped by the Tenth Doctor, Sheldrake was confronted by the Time Lord and SSS agents. Unconcerned, Sheldrake pointed out that the temporal chaos had destroyed any evidence they had on him, forcing the SSS to release him. The Doctor pointed out though that Sheldrake was likely to be blamed for the disaster by the public, destroying his reputation and making him liable for numerous lawsuits that would bankrupt him. Realising that the Doctor was right, Sheldrake begged the agents to arrest him but they just walked away from him. (AUDIO: The Wrong Woman)
