While I would not call "My Friend, My Enemy" a great episode of "Hawaii Five-O", it certainly is a strong one--and proof that after almost 10 complete seasons that the show was still very well made.
This show has to do with a king of some fictional Arab country. His wife ends up getting kidnapped AFTER a feisty Italian reporter publishes an article saying that there would be such a kidnapping! Not surprisingly, McGarrett wants to know how she knew, but being a reporter with high ideals, she refuses to divulge her source and the source is adamant that he does not want to talk with the police. Into this odd mix comes a king's first wife--a lady who is hiding a secret of her own.
Apart from watching McGarrett and Danno making sexist leers at the cute reporter, this is a very good episode. The script is interesting, has a few nice twists and kept my interest. Worth seeing.
