Miles Barrington Smythe

Miles Barrington Smythe (most likely an alias) was a Russian spy working undercover in London in 1963.

Biography
Miles worked with the MI6 double agent Barker. On 23rd November, 1963, Miles left secret documents for Barker which instructed him to use his government employee card to access information, in William Pike's cab before being arrested by the Police. Bill Pike was taken to a police station along with Jorjie Turner from 2050, due to her strange communications device. Bill was sent to be interrogated by Barker while Miles took his place in the cell with Jorjie. K9 Mark 2 and Starkey arrived at the cell and set them both free. K9 created a distraction using a car crash sound effect, Miles then alerted the Constable to a "jolly awful crash", the Constable recognised him and chased him throughout the station. However, Miles catched up with the team in the interrogation room. K9 proved that Bill was innocent by scanning the document, he detected the language as Russian and that there was a coded message. Based on a basic mathematical equation, the details of a spy network located in the area. Barker insisted it only proved Bill was guilty and tried to leave but was stopped by blast from K9. He detected that the message was to a spy instructing him to use his government employee card to access information and as Bill was not a government employee, he was proven innocent. K9 tried to find who the name of the spy was but the document self-destructed before he do so. Starkey, Darius and K9 later returned to their own time as Bill was let free.

Barker later met with Miles to discuss their close escape, he complained that Miles took his time setting the self-destruct and that "the mechanical-dog" almost revealed him. Miles told him he was interested to see it's capabilities, Barker hoped the next time he passed material on to him he'd take better care of it. Miles argued that he needed to hide it quickly and the Cab was convinient, Barker handed him a spare copy of the Document. Miles appreciated this and hoped that one day soon Britain would enjoy the kind of society he did. (K9TV: The Cambridge Spy)
