1.14. Passing by a window, you see two dead men in a
room, with a gun and a deck of cards. (KK2)

1.14 answer: You’re a diver, going past a window of a sunken submarine
(or ship). The two men were in a sinking vessel; they had a gun but only
one bullet. Neither wanted to drown, so they played cards to see who would
get the bullet. The loser shot the winner (or else the winner shot
himself), and then the loser drowned when the room filled up with water.
