Afraid that someone had heard me, I froze in place. I felt a little claustrophobic hunched down on my hands and knees inside the air duct I was crawling through. Catching a glimpse of the people in the room below me, I hoped that no one would look up and notice my face staring out through the hole in the vent. I strained my ears to try and pick up threads of conversation from the cacophony rising up from the crowd, praying that I would not be discovered and my cover blown. World traveler, expat trailing spouse, mom to three kids, prone to occasional bouts of daftness. It's the perfect cover for a spy.
