Here! (I seem to be sticking on 'in Space!' for everybody for some reason, though, so am skipping that):

Wild West
Liz had been determined to become a doctor, but despite battling her way to a degree, she had not been allowed to be formally awarded it. At least out here, they didn’t care much who was the sawbones as long as they didn’t kill too many of their patients – and there were plenty of patients to practice on, especially with Sheriff Lethbridge-Stewart around.

Coffee Shop
“I think I’ve got it this time,” said Liz as she frowned over her notes in the search of the formula for a perfect espresso. “Now, Benton, try this…”

Shapeshifters
She called it a curse and kept herself in the lab for hours trying to work out how to undo the effects of the bite, but somehow, racing out on four legs in the moonlight, there was a part of her that revelled in the freedom.

Pirates
“Don’t worry, Captain,” said Liz to her latest captive. “I won’t hurt you. At least, not as long as you hand over your cargo right now!”

Born Another Gender
David Shaw, his tutors said, had a brilliant mind and did well enough, but he seemed to lack the drive needed to propel him to the heights he was capable of – a need to prove himself, perhaps.

Schoolfic
Liz scrunched up another of the mean, anonymous letters and threw it into the fire. Sarah Jane caught it.

“Evidence,” she said, when Liz looked at her. “We might need it.”

“I don’t understand why anyone would hate me,” she said. “What did I do?”

Jo sighed. “Well, maybe if you came last in something just once in a while, it might help,” she offered and then shrugged at their looks. “It works for me.”

Police/Firefighters
“Look, Dr Shaw, I assure you I didn’t murder that man and if you’re the brilliant forensics expert you claim and not a numbskull like DI Stewart here, you’ll soon realise it!”

Liz gave the prisoner a sharp look, raising an eyebrow at his eccentric clothing – but on the other hand, there was something very odd about that dead body…

Urban Fantasy
“Fairies?” said Liz, not even bothering to hide her laughter. “And is this why you’ve summoned me here from Cambridge, Brigadier? You must be mad!”

“Not just fairies, Miss Shaw – UNIT has been set up to deal with vampires, werewolves, leprechauns –”

“What,” she said, in scornful disbelief, “not little green men?”

Regency
Brigadier Lethbridge-Stewart was, Miss Elizabeth Shaw decided, the most infuriating, patronising man she had ever met. Unfortunately, he also seemed to be the only gentleman in the district who wasn’t completely terrified of her reputation as a bluestocking…

Okay, it has been a long while since I've read These Old Shades so bear with me. Also I seem to be incapable of doing the 'in space' one for anyone so far, so I'm striking it out of the meme! Here goes:

Wild West
The Sheriff opened his mouth to object to the shooting and then took one look at the Devil’s face and decided that discretion was the better part of valour and it wasn’t as if the dead man hadn’t been the worst kind of villain anyhow.

Coffee Shop
Avon raised his eyebrow fractionally on hearing shouts coming from the coffee shop. It seemed, he thought, that Justin and Léonie had been making a mess of the business again and he regretfully bestirred himself to go and deal with the inevitable ensuing confusion of orders.

Shapeshifters
One should, Avon reflected rather belatedly, perhaps be more careful about the strays one picked up. . .

Pirates
“But we were after a treasure map!” said Léonie. “Gold, enfin! Not – what is this? Crates and crates of it!”

“Burgundy,” said Avon. “Rupert does have a nose for it. And I must admit, it would have been a crime to let the sea water ruin it.”

Born Another Gender
The Earl of Tenbury had been far too persistent. Justine Alastair had been forced to take measures.

“’Pon rep,” said Rupert, who’d run into the room on hearing the loud report. “The fellow was as rich as they come! Couldn’t you wed him first and shot him after?”

Justine gave a shudder. The man had clammy hands and was far too fond of onions. “I fear not. Come, Rupert, you must help me dispose of the body.”

Schoolfic
Devil Alastair, Terror of the Sixth, pushed aside the last of the Forth Form bullies to lend a hand to the scruffy and battered First Former lying in the mud of the school field. “Up with you, and cease that snivelling. What is your name?”

“Leon,” said the new boy.

Police/Firefighters
Detective Inspector Alastair waited until he had heard the sound of gunshots die down and then gave the nod to the waiting Sergeant Davenant. “Since the villains have now ceased obliging us by killing each other – time to round up the survivors!”

Urban Fantasy
“When will you learn?” Avon said to Rupert, leading him out of the strangely sunny glade. “Such flowers in bloom in January, leaves on the trees – clear markers of the uncanny. One must keep a watch for these things and take precautions – bring protective charms – or iron perhaps,” he added, somehow skewering a fairy who had not been their before with his blade. He withdrew it and glanced at his brother. “However, steel will do.”

Regency
(I know TOS is technically not Regency, but it is Heyer, so it does seem a bit redundant!)

Thank you! I liked them, too. :-)
