Prince Blueblood dislikes being secret agent Double-O-Zeta, but since no pony does it better, the princesses won't let him quit. Trailing the mad unicorn Green Briar to Ponyville, though, Blueblood runs into Rainbow Dash, already investigating the odd new pony in the area. She resents this jerkwad of a prince suddenly butting in, and when circumstances force the two to work together, the unexpected feelings they arouse in each other might prove more dangerous than anything Green Briar has planned.
Inspired by TAW's Shipping Contest and finished with much thanks to Casca on mlpchan's /fic/ board, Aquillo and cheeze sauce over at Saltblock, and Bad Horse, Cloudy Skies and Skywriter here at FiMFiction. The adventure continues as well in the second Clandestine Corps adventure, Piefall!
