P.R.O.B.E.

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?

When P.R.O.B.E. are summoned to investigate the savage murder of retired headmaster Mr. Whittaker and his dog, Liz Shaw is disturbed to find evidence of a satanic ritual near the scene of the crime. The trail leads of deceit and corruption extends to the current occupants of nearby Winterborne School, where it appears that someone is determined to cover up an ancient secret – at any cost. With another animal having bit the dust, the current headteacher accused of murdering a pupil, and one of the school's oldest employees having been stabbed with a knife, Liz finds herself under increasing pressure from all sides to produce results, especially with P.R.O.B.E. under threat from within – and the death toll mounting. However, a shocking revelation from headteacher Gavin Purcell reveals that The Devil of Winterborne is at large – and only Liz can stop it.

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?

The Devil of Winterborne 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?
