Have any of you ever heard of the riddle of the werewolf wife I need an answer to it.
It goes something like this
U are stranded on an island and the man and there is an old man. He say's he will help u get off this island under one condition, u must marry one of his three daughters. 1 of his daughters always tell the truth, the 2nd daughter always lies, and the third daughter sometimes lies and sometimes tells the truth but she is a werewolf. You don't care which daughter u marry as long as its not the werewolf because she will kill you. You are given a chance to ask only 1 question to the three girls to figure out who u can marry. What do u ask ?

It exists in these forums in about 3 or 4 different versions. The trick is to ask a question of 1 daughter about a second, such that both the truth-teller and liar will answer the same, and will let you know if the 2nd daughter is a werewolf, assuming the first is not. The answer will guarantee in all cases that one of the daughters is not the werewolf.
"Abigail, if I were to ask you if Becky is the werewolf, what would you answer?" If she answers yes, marry Carla. If she answers no, marry Becky.

Im sorry but that dosent solve the riddle
Case point
Abigail-Liar
Becky-Werwolf
Carla-Truth Teller
"Abigail, if I were to ask you if Becky is the werewolf, what would you answer?" If she answers yes, marry Carla. If she answers no, marry Becky.
U would marry the werewolf by your reasoning because Abigial would be forced to lie and u would pick becky which is the werewolf

Actually, she would be forced to tell the truth. It is a standard method to force "reliable liars" to tell the truth.
Concider: "What would you say if I asked you if Becky is the warewolf?" != "Is Becky a warewolf?". In the first case, if asked, she would lie, and therefore "would" say 'No'. Hence, she must lie in answer of the question and say 'Yes' -- which is the truth.
