The Islet Mystery 32

They all sailed off to another beautiful island, which led to the inviting emerald-green lagoons. The rows of verdant hills on either side, the blue-and-white clouds, and the kaleidoscopic world beneath the sea level stood as flawless ensembles of nature's world of art. With the white yacht moving in her full grace ahead of them, they trailed along in a row through their canoes, leaving white foams tailing behind them.

The yacht pulled over the side of an island a few minutes later, at the entrance to a lagoon. Everyone received the instruction that the control would be turned off so that they could go around paddling by themselves. They could stop anywhere to do snorkeling or go inside the caves as long as they go by groups.
