Long ago and far away, the Doctor and Leela faced the Robots of Death…

To a society dependant on robots, the news that these benign, tireless, obedient labourers could be turned into killers would cause panic.  So it was kept a secret.  In Kaldor City, only three survivors of the Sandminer massacre know the truth.  But now, several years later, they are beginning to show signs of mental breakdown.  And once again, the robots are being programmed to kill.  Can the dead genius Taren Capel possibly be involved in this new outrage?

Worst of all, this time the deadly robots are not confined to a Sandminer.  This time they are loose in Kaldor City.  And this time, unless the Doctor and Leela can stop them, they really will destroy the world…

Eager for solitude away from the TARDIS and the endlessly inquisitive Leela, the Doctor steps out on to a benign-looking planet.  But the apparent tranquility hides a terrifying secret...

The TARDIS has arrived on a world of violence, where hideous creatures hunt and kill endlessly, vying for supremacy at the top of the food chain.  But is evolution on the planet natural or engineered by some higher power?  And why has an aggressively suspicious alien police force sent a secret mission here?

With no one safe from the planet's tireless predators, Leela's warrior instincts are tensed to the full.  The Doctor, meanwhile, begins to suspect that there is a scientific purpose to the planet - one married to a sinister intelligence.

Whatever the data being collated from the planet, the Doctor soon realises its usage may have far-reaching consequences for all humanity...

It's Reading Week at the University of East Wessex, but not everything comes to a stop.

The wood is still haunted.  Experiments in telepathy, remote viewing, precognition and other paranormal phenomena continue in the Parapsychology Department.  The department deads still think the Kellerfield Research Fellow is out for publicity rather than psychic results.  A grizzly murder remains unsolved by local police.  The students are still holding seances in the graveyard.

When the TARDIS arrives in Norswood, the Doctor and Leela are caught up in events that are spiralling out of control.  Leela is chased by a phantom, and the Doctor takes the waters.  But soon it isn't just the Parapsychology Department's funding that's in question - it's the whole of existence.
