No matter how inevitable the situation seems to be at first glance, there may be some logical alternatives, we can think of, to avoid it. That is what “hope” matters.
The necklace, the Diamond of Hope, was brought to the gypsy for three times. It was a very precious, famous but cursed necklace, which brought misfortune to whomever that possessed it. His partner, the demon monkey trained by him as a thief, brought it to him. The monkey stole it from the royal princess visiting the Rock of Gibraltar with her queen mother. Such a large stone, specially owned by the royal family, must be very difficult to be sold. Therefore the gypsy sent it back to the princess for the first two times with a warning note to pay more attention to the gem. Despite of his effort, the necklace returned to him for the third time. The monkey who brought it was shot to death by the royal guard. Three times!! It means something. He was sure then to be singled out by the necklace and possessed the misfortune at the same time.
One night with a full moon, the gypsy swam a mile off the shore, where the Gibraltar Trench, a mile deep trench, located. There he dropped the necklace so that he thought nobody could reach it any more. With content he started sluggish swimming back to the shore. Simultaneously the necklace was falling down toward the bottom but it reached the dorsal fin of a sleeping shark. The shark woke up and swam upward to the surface of the sea, where the gypsy was still swimming sluggishly. It was the gypsy who was very surprised to see the necklace again, shouted, and cut a splash. In the dark night he couldn’t recognize the shark’s fin but the only the necklace, as if it had been moving in the air. “Is this a miracle or only my delusion ?” he thought. The shark noticed the gypsy and began swimming toward him and so did he toward the necklace (or the shark).
The story ended here.
It is very likely that you imagine the gypsy got killed. However as far as the word “hope” is concerned, we can think the following reasons to avoid it.
1. The gypsy must smell different to the shark in such an odd situation.
2. The gypsy is an animal trainer.
3. The shark was chosen by the necklace.

On the Rock of Gibraltar, there was a monkey. It was trained by a gypsy. It sneaked into rooms of the hotels and stole jewels for the gypsy.
One day the monkey stole a necklace from the princess of Great Britain. The necklace was famous for its big diamond, the Diamond of Hope. The diamond had a story that the great misfortune had happened to whoever owned it. The gypsy tried in vain to return the necklace to the princess. When his monkey died under a curse, he realized that he was chosen to save the princess from the curse.
One night he dropped the necklace into the Gibraltar Trench so as not to be found by anyone. It meant to him that the curse on the necklace could not bring any more misfortune to anybody. The necklace was supposed to be lost in the deep sea forever. However the curse on the diamond was much stronger than expected. It chose a shark as its next owner, and the shark with the diamond on the dorsal fin was coming closer to the gypsy.
The gypsy's misfortune seems to be inevitable. Is there any hope for him? The answer is "Yes." As far as we can imagine an alternative ending to save the gypsy, there must be hope.

さて、今回の作品はその名を「Diamond of Hope」、世界一大きなダイヤモンドのネックレスが主人公（？）。ジプシーの訓練したお猿さん、どうしてそう何度も同じでっかいダイヤを盗んだのか。
それは、やっぱり、ダイヤに魅入られたんでしょうね。
実在する青いダイヤのホープはマリアントワネットやマリリン・モンローが所有していたとか。不運をもたらす呪いのダイヤ。
面白い話ですが、私は呪いは信じないです。でも、ダイヤの力っていうのはあるかも！　そんなに大きなダイヤモンドを持っていたら、自分は特別な選ばれた人間だって思えることでしょうね。
さて、結末、どうなったんでしょうね。ジプシーは。
希望。どんなときにも持とうと思えば、もてるものだと私は思います。（きっと作者も）
