Forensic Exit pass 4/5

A lovely cashmere sweater was found torn to shreds (What a Crime!!) on the sidewalk in the international quarter.

The sweater police talked to six witnesses, including the shredder. The six were very open about what had happened. The only trouble was that none of them spoke any language the police could understand. Nevertheless, the police were able to piece together the following information: The witnesses were three men and three women: Fred, John and William; Gloria,

Gilda, and Barbara

The men were married to the women, though not necessarily in the order listed.

William's wife was the cashmere murderer.

Fred speaks and understands only Basque.

John is bald.

The couple who live next door to Gilda and her husband have the same color hair she does, and speak both Spanish and Basque.

William's wife recently gave Barbara a home perm.

Gilda's husband speaks only French.

Who destroyed the lovely sweater? Explain your answer!

 Solution to the Wife Puzzle

 If you can identify William's wife, you'll know the shredder. William's wife isn't Barbara, because the former gave the latter a permanent. William's wife must be either Gilda or Gloria.

 Fred's wife isn't Gilda, because he speaks only Basque and her husband speaks only French. So Fred's wife is either

Gloria or Barbara.

 If John is bald, he doesn't live next door to Gilda and he doesn't speak Spanish and Basque.

 Therefore, John must speak French and be married to

Gilda. Only Gloria can be William's wife and the horrible cashmere shredder.
