Alfred Hitchcock Presents: None Are So Blind (1956)

Seymour Johnston is a vain, silly man, but that's not how he sees himself. Nor does he see himself the way his late father did--as a man who couldn't be trusted with a large inheritance, a man who needed to make his own way in the world. That's why Seymour's father left all his money to his sister, Seymour's Aunt Muriel. Of course, once she is dead, the money will all go to him. But the middle-aged Aunt Muriel does not seem destined to die any time soon. In the meantime, how will Seymour keep his antique shop going? More important, how will he be able to enjoy any of the finer things in life? When Seymour, reduced to eating in a diner, finds a wallet someone had dropped, the answer comes to him immediately.
