Which casket is the picture in?

It’s in the silver casket.

So which clue was the one true one? The gold one was not true, the silver one is not true, but the lead one was true. BUT….I think I have it. I’ve been assuming that the clue that was true meant that that was where the picture was. But that’s not necessarily true.

Lead.

If only one clue is true, then the other two must be false.
If gold is true, then the negation of the silver clue contradicts the gold.
If silver was , then inverse lead contradicts silver.
Only lead stays logically consistent.

Which means it is in the silver casket

Lead was my first reaction too @ragingloli.

I think the one true one is the Lead saying “It’s not in the gold” which makes Gold’s and Silver’s false so it’s in the silver.

I got there first! Ha!

Were the caskets locked or something?
A clever suitor would have opened all three.

Well, the clues were ON the caskets. Not in them. And they were required to guess based on the clues.

I’d be more worried about the King. Any suitor would find him meddlesome, and probably a control freak. I wonder if he would let his daughter alone and let her come to love the suitor, or if he would be butting in the whole time.

If I were the suitor, I’d say “this dude is loony – the girl ain’t worth it” – and scoot.

He’s a king. He has far more than love on his mind. Alliances to be made. She doesn’t have a choice in the matter.

If it were in the gold casket, then both gold and silver would be true, so that doesn’t work.
If it were in the lead casket, then both silver and lead would be true, so that doesn’t work.
If it’s in the silver casket, then only lead is true, so that’s your answer.

Yep.

None of the above. Dracula is in the silver casket. Frankenstein and The Mummy are in the other two. The picture bit is a ploy.
