Publisher's summary
The colonists knew the risks about Jegg-Sau. With a flimsy atmosphere, no mineral wealth and exhausted soil, only the strongest and most determined could hope to make a home there. But with nowhere else to go, they went ahead, allegedly funded by a stock of valuable relics and art treasures stolen from Earth...

But the colony failed. Jegg-Sau was deserted once more, a home only to carrion and rusted dreams. But Bernice Summerfield believes the relics remained, and she’s come a long, long way in search of them. What she’ll find is that others have reached Jegg-Sau before her. She’ll find herself cat’s-paw in a dark outpost of frailty and obsession.

And she’ll find the robots.

Cast

 * Bernice Summerfield - Lisa Bowerman
 * Robot - Michael Kilgarriff
 * Ethan Kalwell - Paul Shelley
 * Elise Kalwell - Katherine Holme

Colony planets

 * Jegg-Sau is a former Earth colony, established in the 25th century. Terraforming destroyed the planet's soil within ten years and the colonists soon abandoned when they could not grow their own food. The Kalwells and K103 live in the environmental dome which were left intact by the departing colonists.

Communications technology

 * Irving Braxiatel had an extra power pack built into the comm panel of Benny's shuttle given her propensity to get into trouble.

Individuals

 * Professor J.P. Kettlewell and his first robot, the Experimental Prototype Robot K1, are mentioned.
 * Kalwell was a failed historian and writer who learned that he was a direct descendant of Professor Kettlewell. Shortly after the Kalwells' arrival on Jegg-Sau, the K1 robots created robotic facsimiles of them. The Kalwells were imprisoned in the dome. Although they eventually escaped, Elise was subsequently killed by the K1 robots.
 * The K1 robots' CPUs are based on human neural pathways whereas they are constructed from living metal, which is what enabled the original K1 robot to grow in size. Kalwell laments that Professor Kettlewell died before filing the patents of these inventions. Otherwise, Kalwell and his ancestors would have been incredibly wealthy.
 * Robert Elliot Whitman, one of the original colonists, kept a journal while on Jegg-Sau. He installed a virtual reality suite which was equipped with a simulation engine. His programme of choice was Pick-Up Bar Babylon, a virtual reality pornography which was made in 2289. His chosen pick-up was named Misty. However, Whitman was still unhappy. He lacked true companionship given that Misty was a simulation.

Languages

 * Benny knows several curses in the Ice Warrior language.

Objects

 * In addition to K103, other artefacts in the Jegg-Sau auction hub include a 1918 painting by Wyndham Lewis, a Samurai sword dating from the 15th century and Egyptian bowls dating from the 3rd century B.C..

Robots

 * K103 was constructed in 2058. Benny describes its design as "retro" and jokingly claims that "you could fit a man inside there." It is designed to operate the Starclimber 3000, which Benny says "takes [her] back to the playground" as it was for children "who couldn't afford a proper bike" by the late 26th century.
 * The Jegg-Sau colonists learned that K103 was capable of constructing robots of the same configuration as itself. When they abandoned the colony, the K1 robots were left behind.

Continuity

 * The Experimental Prototype Robot K1 first appeared in TV: Robot.
 * Kalwell tells Benny that the original K1 robot grew in size due to its construction from living metal. However, the incident was subsequently covered up by UNIT. (TV: Robot)
