Claire Price had a ghostly experience in Glasgow this year when she returned to film the new Rebus series.
"I walked into the flat with my driver Ewan and it was a lovely place at the top of a tenement. However the minute I set foot inside, I knew it was haunted," explains Claire.
"It was very, very cold and had a strange feeling about it. There was a water bed in the flat and the first night I tried to go to sleep, someone tried to push me off from underneath. It sounds mad, but it happened, and then the bedroom door rattled all night.
"The ghost really didn't want me there although by the end of the week, when he knew I was moving on, I think we became friends!"
This season Siobhan finds a regained trust in her Inspector, played by Ken Stott.
"I'm really glad my character has absolute loyalty to Rebus again in this series. Even though he tests her to the limit in the first story, her trust in him is a given and she knows he would never do anything inherently wrong. Rebus compromises himself deeply, but Siobhan doesn't doubt him.
"In fact in the books, Siobhan and Templar never doubt Rebus. Their trust is absolute and they know the goodness that is within him. It is his male contemporaries who think he's a dodgy cop and try to catch him out."
Claire continues: "There is a lot of tension between my character and Templar, played by Jennifer Black, this time around. It's been growing gradually as Siobhan and Templar develop a relationship.
"Whereas before she was very much Rebus' protégé and partner, at the same time she is now going off and working to Templar too.
"At his worst moments, Rebus treats Siobhan like a glorified PA and yet within that there is a lot of respect. But I think Templar sees a lot of herself in Siobhan and wants to cultivate her.
"There will come a time when Siobhan must choose whether or not to surpass Rebus, leaving behind that rookie/hero partnership, and Rebus is aware of that at times."
Like a long line of television sidekicks before her, Claire knows it is the job of the sergeant to do the leg work.
"From his Morse days, Kevin Whately would understand that," she laughs. "You have the sergeant who is practical and, like the foot soldier, he does the interviews and the boring stuff so the Detective Inspector can have his eureka moment.
"With Morse, he put on his classical music and fell asleep. With Rebus, he goes to the pub and drinks and plays the one-armed bandit.
"It's the difference between having to learn your discipline, which is what Siobhan is doing, or like Rebus, riffing on the rules once you have learnt them."
Although Claire recalls the episode in which she steps in to save the day. She adds: "That was really exciting to shoot, because I didn't realise how powerful Siobhan is.
"She begins to turn into Rebus, because she does what he instinctively would do; she bends the rules in order to save him. Even though she does this out of integrity, it is something other coppers wouldn't have done."
Another job of the sergeant is to drive her Inspector while on a job. But, until the end of the last series, Claire didn't hold a full licence and so was unable to drive.
"Last year I was so proud of my driving because I'd been having frantic lessons in order to pass and then, when I passed, I did lots of driving and it felt very natural.
"However back in London I don't have a car so when I went up to film in February, I hadn't been behind a wheel for six months and was very shaky. Every take I would do in the car, the director would say great but can you do that five times faster. There I was mirror, signal, manoeuvre like Miss Marple and they wanted speed and action!
"So in the end they wrote in a car accident for me as a joke, which I thought was most unfair…"
