Mystery of the Ancient Temple

Once upon a time there existed a temple in India which housed three identical idols which spoke to the devotees.

The idols were of – God of Truth, which always spoke the truth; God of Falsehood, which always lied; and God of Diplomacy which sometimes spoke the truth and at other times lied.

The pilgrims come from all parts of the world to get their questions answered by the Gods. But there was a problem. As the idols were indistinguishable, devotees were not sure from which idol to ask their questions and in turn they did not know which God has answered and whether to believe it or not.

Once a wise man visited the temple. He asked the question: “Which God is seated at the centre?” to all the three idols. The idol on the left, centre and right replied God of Truth, God of Diplomacy and God of Falsehood respectively. The wise man at once proclaimed that he had solved the mystery of the temple.

Riddle Answer

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?
