The Islet Mystery 23

As far as she could remember, the arch of the cove stood like a towering, archeological pillar of stones, spreading like a gateway to the paradise beneath it. It formed a wide, rocky canopy to a vast area, several miles away from the entrance. However, one could only appreciate it during low tide. Glistening stalactites and stalagmites spread all over the canopy, giving anyone a memorable experience in canoeing within the area.

On the far end, stood a beach house owned by Ryan's family, and even without asking, she knew their laboratory was not far from there. However, the area covered by the cove could only be appreciated during low tide because the water level would rise and fill the whole place during high tide. The sea level would then shut the entrance to the beautiful haven inside. The people living there should know when to get in and out.
