Spy Glass is a private investigator, hired by the princess herself for a very special task: To find and arrest changling spys she suspects to be placed all around Canterlot. He is especially happy to hear that the pay will be great enough to get his life started with his wife, Melony, and his soon to be born foal.
But once he makes a shocking discovery, he will have to make a decision that will either crush his dreams, or begin his future!

Note: This story takes place after the Changeling Invasion, Long before they've been reformed. In this alternate timeline Changelings do not reform into colorful beings when reformed, nor does the entire race reform at once. But I hope you like the story anyway^^
