Doctor Who Season 8 Episode 1: Terror of the Autons (blog part two)

from a long distance. 

At a circus, a lorry materialises out of thin air with the distinctive sound of a TARDIS. The occupant is a thin, bearded man dressed in a black suit who introduces himself as the Master to the circus owner, Rossini (though his real name is Russell), and hypnotises him.

Subsequently, the Master and Russell break into the National Space Museum and steal a translucent plastic polyhedron, one of the energy units used by the Nestene Consciousness in their attempted invasion of Earth. The Master then takes the energy unit to a radio telescope facility, killing the technician on duty with a weapon that shrinks the victim, leaving a twisted, doll-sized body.

The Master then hooks up the energy unit to the radio telescope and sends a signal into space.
