The Queen of Spades (opera)
Later, the ghost of the grandmother comes to Hermann and tells him the three secret cards: Three, Seven, Ace.  Hermann’s mind is now on one thing: he must go to casino and play cards and win.  Lisa drowns herself in  a river.  Hermann gambles all his money at the casino, saying "The life is only game and the sure is only death".  The first two cards are the Three and the Seven, but the third card is not the Ace, it is the Queen of Spades.  The old grandmother’s ghost comes again to Hermann.  Hermann kills himself.
