The Queen of Spades
"A gambling countess comes by a secret three card combination that wins her a fortune, but she is allowed to use it only once and not gamble again. She passes on the info twice, and the recipients both die violently. She is warned that if she passes it on again, she too will die. Many years later, a young soldier discovers that the countess has the secret, and he resolves to get it out of her."
