Many years ago, when she was travelling with the Doctor, Jo Grant visited Zayin Eight. Now, suddenly and inexplicably, she is back on that ravaged planet, and reunited with a human called Newton Calder. What happened to the missing members of Calder's team? What is the secret of the vast ruined city? The answers will lie in the dark and distant past of the Time Lords themselves...
The Zayin system is located in the Argo Navis Cluster, 80 years from Earth.
Calder, Anyetta, Alein and Tomis are affiliated with the Space Archaeology Group (SAG). They are exploring the remnants of an ancient civilisation which were detected by a passing probe.
Jo's grandfather, who smoked a pipe, always used to spoil her when she was a child. He often bought her ice cream behind her parents' backs, observing, "What's the harm? Life's too short." He died in 1958 when his granddaughter was seven years old.
