Duo: The girl with a secret

The girl with a secret: Alice knew her new husband had a checkered past --he was in undercover police work before their marriage. He was supposed to be out of that now. But just as they arrive for a visit to meet his family, he gets called away to infiltrate a narcotics gang. Alice finds out, totally by accident. Tony is ready to call the whole thing off. But he goes to Mexico, and Alice is set to cover for him. But it's harder to keep the secret than she expects, and the danger is all around. Incident at a corner: In this story adapted for television and produced by Alfred Hitchcock, a school crossing guard reprimands the PTA president for careless driving. He is later dismissed from his job on the basis of an anonymous note accusing him of being too friendly with little schoolgirls. His daughter's boyfriend takes up his cause, assuming that the PTA president sent the note out of spite. It turns out that the note was sent by a woman living across the street from the school, who knew the guard from another city, and feared he would expose her past life. Story is told with the same incident repeated from several different viewpoints.
