Poisoned Apple

Lucretia Borgia invited a prospective victim to lunch. They ate a hearty meal of roast venison, with a selection of fresh vegetables, all washed down with the finest wine imported from Bordeaux in France.

After the meal they finished off with figs and grapes freshly picked.

“Just one apple left”, said Lucretia, “I insist you have that. “No”, said the guest, “I couldn’t”. “Tell you what”, said Lucretia, “we will share it”, and promptly sliced it neatly in two with her sharpest knife. The guest and Lucretia started to eat their respective halves when suddenly the guest’s eyes rolled towards the ceiling and he keeled over backwards stone dead.

“Another victim successfully despatched,” thought Lucretia.

Why was Lucretia not poisoned after eating the apple?

Riddle Answer

Anna’s Picture

Once upon a time there was a beautiful princess named Anna. Anna’s father, the King, wanted to be sure his daughter married an intelligent man.

To test his daughter’s suitors the King hid Anna’s picture in one of three boxes. The suitor had to be able to select the box with Anna’s picture on one try and within twenty seconds.

The following messages were written on the boxes.

Gold box: Anna’s picture is in this box.
Silver box: Anna’s picture is not in this box.
Bronze box: Anna’s picture is not in the gold box.

The King would tell each suitor, “Only one of the three messages is correct.” Which box contained Anna’s picture?
