A/N: So I'm back with a new multi-chaptered story. I've been at it for quite a while, even before series 9, so the story ignores all that happened there. It contains several things I've wanted to explore for a while, so it's all here. I've also snagged a character that CatS81 invented and ran amuck with it - but Cat kindly allowed me to do so, so it's all good. As I go off with this, I'd once again like to thank my support team - and...though being part of the team ;o) - ShadowSamurai83 for betaing (quite a few chapters more than once). You are all stars!

Title: Toccata

Rating: T+ (for swearing)

Disclaimer: I own nothing. Not even the main OC here (That was Cats81's idea).

Summary: Grace and Boyd find themselves in quite a spot of trouble and the Home Office has an incredible idea who should help out.

Enjoy.

"Toccata"

Ouverture

He had been sitting in the car for days. Hours and hours of inconspicuous driving, of sitting and watching. It was only interrupted sometimes by taking the tube or the bus, and slinking through supermarkets or along the high streets. Then it was back to sitting in the car and watching. Either in this quiet side road, where they were bound to be noticed soon, or in the public parking lot, in the hopes of not missing the decisive moment.

It was a tedious thing, trying his patience; especially since there was no result, despite close to two weeks of observation. There was just nothing to grasp, no particular point where one could make a catch.

The target was just never really alone. There was always somebody around. Usually the same person. A man. It was interesting to watch and just that little bit suspicious. The watcher had to admit, what he saw made a lot of sense, all things considered.

"So, that's her?"

"Yes," the watcher replied, disturbed by the fact that today he had been joined by another person. He wasn't happy about it. It made the small space inside the car even more confined, emotions adding to the pressure inside.

"Not much to look at, that Grace Foley." The comment was spit out with derision and more than a little loathing, and the watcher thought it smart to remain silent.

"Who's that man with her?"

"Peter Boyd," the watcher replied.

"Do you have to be so short in your information? Who is he?" The companion was quickly losing patience, annoyance marking the question.

In response, the watcher shrugged. "A colleague. Friend, caretaker, lover, husband. Who knows? Could be anything. He's hanging around her all the time."

"Handsome man." This time there was a spark of interest in the other person's voice. "Wonder what he sees in her?"

Once again, the watcher didn't answer as they both focused on the couple on the other side of the street. The unfolding scene had a certain tenderness to it, as the man helped the woman, who had been identified as Grace Foley, into the passenger seat of his car.

The couple exchanged a few words and a smile, the man rolling his eyes, before he pulled up Foley's hand and pressed a kiss to the back of it.

"Must be love," the watcher remarked.

His companion snorted derisively. "Love! I wonder what lover boy would think of her if he knew all about her..."

Thank you for reading. Comments would be greatly appreciated.
