A/N - I've only just started watching the Dempsey and Makepeace series on ITV iPlayer, and it's great. I especially liked the episode where Dempsey had a psychotic admirer, an episode with the great Elisabeth Sladen, better known as Sarah Jane Smith from Doctor Who.

I known nothing, but please let me know what you think.

Obsession.

As Harriet 'Harry' Makepeace finally left Dempsey, she couldn't help but think of the recent case, and her own relationship with the New York copper, and how the mess with Cathy had shaped their relationship, although what it would lead to she had no idea.

While she had found Dempsey slightly arrogant and full of himself when they had first met, she had to admit he was good at what he did even if his gung-ho attitude sometimes left much to be desired, especially since they came from different worlds, but she hadn't expected something like this happening; Harriet had heard of women taking things too far when they'd obsessed over a man, but she had never heard of the lengths Cathy had gone during her insane little rampage, and she wondered how on Earth Cathy had become so obsessed with a man whom she barely knew, but had created fantasy worlds where he'd swept her off of her feet, declaring his undying love for her, like she was a princess in a fairy tale.

Harriet could understand the attraction; in many ways, Dempsey was like Han Solo, with his cool, cocky demeanour which hid the mind of a man who thought on his feet, but even Dempsey had his limits and Cathy had reached them. When she had first seen Star Wars, Harriet had been with friends who'd wanted to see the new sci-fi epic everyone was speaking about, and although it wasn't her cup of tea, she had to admit it was fun, but Han Solo was her favourite character, who'd been more down to earth even if it were clear he was a scoundrel who truly did not want to know anything about the Jedi.

In many ways Dempsey was like Solo; both were cocky, good with guns (despite Spiking's views on the matter), but both of them were incredibly smart in their own way and capable of thinking on their feet. But she had a feeling Solo wouldn't know what to do about a woman any more than Dempsey would, and by that she meant romance despite the fact there was a connection between them.

Cathy had been insane, and Harriet wondered what the hell the other woman had done for the security services before ending up as a waitress, and she guessed it must have been a comedown, and it had something to do with her psychopathy.

She had murdered an innocent man when she'd been aiming for Dempsey's head, and he got out of the way at the last minute. A man with a wife, children…

And she hadn't cared.

Harriet had met dozens of murderers during her career, many of them showing no remorse, but after seeing the way Cathy had fantasised about Dempsey, a man who barely even knew her, she wondered why on Earth the woman had taken that step. But one thing was for sure, Cathy had been dismissive of the things she'd done.

She had broken into Dempsey's flat God alone knew how many times, bugging the place using her expertise and whatever resources she had left from her days in the security services. There was no indication of when this all started, but Harriet was willing to bet Cathy had just let it happen gradually although why she would take the steps she had recently would be a mystery forever.

But the funny thing was…. Harriet hadn't even realised how obsessive the woman was with Dempsey until they'd discovered she lived on the other side of the court, visited her flat and found all of those pictures of Dempsey she'd had taken over the months and stuck to the wall, and destroyed because she'd been so wound up listening to him and her flirting together until she went mad.

Strange thing, love, although what Cathy thought of as love was an obsession.

And it had cost her her life.
