Two skeletons, a man and a woman killed ten years ago, are discovered. One of them comprise the remains of the former right-hand man of Mondrago, a prominent businessman. McGarrett concludes Mondrago is hiding something and may have killed his late wife and his former business associate. Mondrago is indeed hiding something, but not what it seems. The key to the mystery is Mondrago's daughter, who looks just like her late mother. Written by Bill Koenig

In many ways, more like a "Movie of the Week" installment instead of "Hawaii Five-O".
15 March 2010 | by (Bradenton, Florida) – See all my reviews

My summary isn't really a criticism of the episode--more of a commentary on the style. Stylistically, this is one of the stranger ones from the series and it played more like a made for TV movie. And, like another astute reviewer stated, it's rather reminiscent of the movie "Laura".

Before I get to the actual episode, there are a few observations about the cast. French-Vietnamese actress France Nuyen makes an appearance. Trekkies will immediately note her as "Elaan of Troyius" from the original "Star Trek. Herbert Lom was the perennially perturbed Chief Inspector Dreyfus from the Pink Panther films. Two interesting acting jobs done by future Five-O members were Herman Wedemeyer ("Duke") playing a judge and Moe Keale ("Truck") from the final (and pretty sad) final season.

The show begins with some archeology students coming upon an old Hawaiian burial site. Most of the bodies are hundreds of years old--but, inexplicably, two are very, very recent--having been murdered about a decade earlier! McGarrett has to try to piece together who they are and who killed them. The problem, however, is that no one is cooperative in the investigation and it's obvious that the mystery is very deep.

Overall, an interesting show but also one that really isn't particularly great. I mostly was annoyed at the idea of a picture of a woman that is so remarkable that people become captivated with it--even McGarrett to an extent. This seemed a bit silly. I did, however, like the solution to the mystery and who the actual killer was. I guessed this correctly about halfway through the episode, but still thought this was pretty clever.
