Just a prompt to see if I can write these kinds of stories.
Depending whether or not this is well received, I'll write a sequel to save some dames!
When I mean they are anthro, with the tag, I mean they can walk on hind legs comfortably. That's it and all there is to it, nothing special.

In a world where Twilight Sparkle never became the Element of Magic, but instead one of the biggest Problem Sleuths in Canterlot, you are now PI Sparkle and you are currently locked inside of your office in Canterlot the week before your retirement.
=> Who is PI Sparkle?
PI Sparkle was a small time consultant detective in Canterlot. She helped the Canterlot Police Department with solving seemingly impossible cases by using her wit, magic, and keen eye to detail. PI Sparkle soon made a name for herself that shook even the most slippery and toughest of criminals alive. Very quickly, she had became Equestria's best Problem Sleuth.
Two years later, PI Sparkle plans to hang up the hat and coat to retire, move to a small town named Ponyville, and become the resident librarian.
But first, she really needs to escape her office in Canterlot.

Inspired by Problem Sleuth.
