* The Zero Imperative
Former UNIT luminary Liz Shaw and her assistant Bayliss are investigating
a series of bizarre murders, all committed near a soon-to-be-closed psychiatric hospital. When the hospital is unexpectedly
reprieved by rich Industrialist Peter Russell events seem to move out of Liz's control. Are the incumbent director of the
clinic, Doctor Dove and his predecessor Doctor O'Kane harbouring the killer? What is the centuries-old horror hidden in the
grounds? And what exactly is the secret of room zero?
* The Devil of Winterbourne
When P.R.O.B.E. is summoned to investigate the savage murder of
a retired headmaster, Liz Shaw is disturbed to find evidence of satanic rite near the scene of the crime. She soon discovers a web of deceit and corruption that extends back in time, threatening the current occupants
of nearby Winterborne school. With P.R.O.B.E. under threat from within and the
death toll mounting, Liz finds herself under increasing pressure from all sides to produce results... The Devil of Winterborne is at large and only Liz can stop it!
* Unnatural Selection
In 1975, the British Government quietly closed down a secret
evolutionary project codenamed BEAGLE, ordering the destruction of all research materials.
Today, the horrific discovery of several oddly mutated bodies alerts Liz Shaw and P.R.O.B.E. to the fact that something
is stalking the original site of project BEAGLE - something which may challenge the very nature of humanity itself! With a crack security team at her disposal, Liz desperately attempts to track down the perverted results
of the project. But who or what is hunting whom?
* Ghosts of Winterbourne
The Devil of Winterbourne has only recently been exorcised
by P.R.O.B.E. But when the body of its last victim disappears, and a book of
black magic spells is stolen from a local museum, Liz Shaw begins to wonder if the ghosts of the past have really been laid
to rest. Forced into an unholy alliance with the school's disgraced headmaster,
Liz must fight not only her own warring emotions, but a festering evil that threatens to corrupt the Earth again after 100
years. But how do you fight a shadow from hell?
