George Meadows (Chameleon)
From Tardis Wiki, the free Doctor Who reference
A Chameleon took over the identity of George Meadows
"Meadows" was eventually exposed by the Second Doctor, who forced him to tell all that he knew. The false Meadows later escaped and tried to stop Samantha Briggs and Jean Rock from finding the bodies of the original airport personnel, but was recaptured by police. After the Doctor defeated the Chameleons, the real Meadows was freed. (TV: The Faceless Ones)
