A government employee is suspected of slipping some sensitive microfilm to an enemy agent during a day at an amusement park. His fiancée swears that he was never out of her sight the whole day, but the government isn’t convinced. Can Griswold find a way to confirm the alibi?

Actually, Griswold breaks the alibi, and even I was able to figure out its basic flaw, which is never a good sign. The story does have the virtue of an interesting set of bookends—Griswold’s three companions maintain a steady silence and refuse to give him an opening for one of his stories, but he manages one via a non sequitur nonetheless.
