Publisher's summary
Earth, 1974. An innocent phone call. Okay, it was a wrong number, but there can't be any harm in that. Can there?

Cast

 * The Doctor - Colin Baker
 * Lauren Hudson - Kate Brown
 * DJ - David Dobson
 * Connie Pickerill - Kerry Skinner

The Doctor

 * The Doctor does not believe in fate.
 * The Doctor quotes Thomas Jefferson when he says, "I'm a great believer in luck, and I find the harder I work the more I have of it."
 * The Doctor is jailed on a charge of trespass at Green Street Police Station under the name of Dr. John Smith.

Individuals

 * Lauren signs the Official Secrets Act.

Organisations

 * It is implied that the "army man" and doctor who visit Lauren in hospital are with UNIT. The Doctor asks Lauren if the latter was "a tall chap with white hair and rather flamboyant clothes". However, the doctor she describes appears to be the Seventh Doctor — and thus the Sixth doesn't recognise him.

Technology

 * The virus, transmittable through telephone conversations, manifested as a six-inch long, metallic-looking worm or snake which wrapped itself around its host's spine. If the worm had not been removed from Lauren's spine, she would have been transformed into a giant slug creature.
 * It is implied that the virus was bio-engineered by the Viyrans.

Music

 * The DJ plays "Blue Starlight" by Steve Silver.

Continuity

 * The Doctor tells Lauren that he has met Thomas Jefferson. (TV: The Lazarus Experiment)
