The Perfect Couple Mystery - S2.E9

Talk about security clearance. Father Dowling and Sister Steve find themselves smack dab in the middle of a top secret security investigation when one of the parishioners is suspected of stealing confidential documents. The case revolves around a spy who really isn't a spy, a mistress who never was and a cheating husband who didn't. Add to the mix a FBI headquarters that never existed and you've got a case that's about as clear as Irish Stew.
