Sea of Souls

The central character is Douglas Monaghan, played by Bill Paterson, who is the head of a parapsychology unit at a fictional university in Glasgow, Scotland.

For this third run the format had been changed with the series now consisting of six individual one-episode stories instead of three two-parters, with the episodes being shown once per week on Saturday nights.

"[1] Prominent guest stars in individual story lines have included Peter Capaldi, Siobhan Redmond, James Fleet, John Guerrasio, Paul McGann, John Hannah, Jeff Rawle and Colin Salmon.

Justine McManus – Dawn Steele After arriving in series two she struggled to gain the respect of co-workers, but one year on is much more self-assured and is enjoying her new-found friendship with Craig.

Right from the beginning it is clear that Justine has several paranormal abilities, she can apparently see the future (which featured in series three episode Oracle), sense things and see the dead.

Craig's new friendship with Justine also leads to him discover her hidden psychic skills, and it's a revelation that has far-reaching implications for him.

Even though they only appear in this series, Monaghan's two assistants, Megan Sharma and Andrew Gemmil, are not formally written out in the concluding story.

Instead of three, two-part mysteries, aired over the course of three weeks, this series offered a more traditional six-week episodic format.

As with the first series, however, the student assistants made their final appearances in the concluding story without their departures being explained.
