Sea Cave Tour
A sea-cave boat tour offers a perfect glow in the dark, and keeps a record of everyone who stays still enough to be seen.

Ben had found the tour online. It promised a sea cave lit from within by bioluminescent plankton, a rare sight on the north coast in autumn, and a chance to float in the glow with nothing but a lantern and the sound of the water. The reviews were glowing. One said it had changed their life.
They booked it as an anniversary treat, the first time either of them had been away since Rosa's sister Ellie drowned in the bay nine years before. Rosa had said she wanted to see the water again.
The pier at Kestrel was quiet on the evening of the fifth. Their boat was small and white, with a canopy over the stern and a single bench running along each side. The skipper was a man with a grey beard and a faded fisherman's jumper. He helped them aboard without speaking, and checked their names against a clipboard, and then tapped the clipboard twice before he handed it back.
"Two?" he said.
"Yes," said Rosa. "Just the two of us."
"Good," said the skipper, and started the engine.

**Guide notes (skipper's annotations, kept on the clipboard)**
*19:02. Departed. Two passengers. Calm sea, slight swell from the north.*
*19:14. Passengers commenting on the light. Light is not yet visible.*
*19:26. Cave mouth in sight. Low tide confirmed. Passengers asked to keep their hands inside the boat.*
*19:31. Passenger (male) asked why there is a third seat on the bench. Seat is unoccupied. Told him it is for the guide. Guide is on board. Passenger looked at the empty seat for some time before turning back.*

The cave mouth opened in the cliff like a black archway. The water inside was still and dark. The skipper cut the engine, and the boat drifted in on the tide, and for a long moment there was nothing to see but the reflection of the lantern on the surface.
Then the water began to glow.
It came up from below, very slowly, a soft blue-green light that spread out from the hull in rings. Where the boat's shadow fell, the water went dark, and where the shadow lifted, the light came back brighter. It was beautiful. Rosa leaned over the side and put her hand in it, and the light ran up her wrist and over her knuckles, cool and bright, and she laughed out loud.
Ben laughed too. He put his hand in the water beside hers. The light ran up his arm.
"Look at it," he said. "It's alive."

**Passenger postcard (received by the Ilett family, 9 November, posted from Kestrel)**
*Dear Mum,*
*We're having the time of our lives. The cave was everything they said and more. Mum says the glow is coming from tiny animals in the water, and that when you touch them they light up to say hello.*
*The guide was very quiet. He had a funny way of counting the seats. I think he was just being thorough.*
*When we came out, it was dark and the pier lights were on. The guide asked if we'd enjoyed the tour, and we said yes, and he said he was glad, and that the cave likes to keep a record of visitors. He said the light only comes up for people who are willing to stay still and let it see them.*
*Mum put her hand on my shoulder and said she felt a little tired. I said I did too, but it was a nice tired. The water was very warm after all that cold air.*
*Love, Dad (and Mum)*

**Kestrel Bay Boat Tours — Internal incident report (6 November)**
*Passengers: 2 (Rosa Ilett, Ben Ilett). Guide: K. Halse. Vessel: Gull Mark II.*
*Passengers returned to the pier at 21:10. Both were in good spirits. Both were wet to the knees, which was not expected, as the boat has a dry deck and the cave is shallow.*
*Passengers asked for a second tour. Booking system shows no record of a second tour. Passengers said they had been told the cave keeps a record of visitors, and would like their names added.*
*Note: the booking confirmation for 5 November lists three passengers, not two. The third name is printed in a neat hand under the others. It is Ellie Mortlock, who was Rosa's sister.*

**Note from K. Halse (guide), 12 November**
I've taken the Gull Mark II out to the cave three times since the Iletts came in. The first two trips were routine. Calm water, light on the water, low tide. The passengers were always two.
On the third trip, I felt the boat's weight change at the mouth of the cave. The bench on the port side dipped, as if someone had sat down on the far end of it. I looked. No one was there.
The water in the cave was very bright. It came up around the hull in a long ring, and in the middle of the ring, very faint, I could make out the shape of a woman sitting in the water, knees folded, hands in her lap, looking up at the boat.
She wasn't floating. She was sitting on the glowing bottom of the cave, perfectly at ease, as if she were on a bench in a garden on a warm day.
I started the engine. I took the boat out past the cliff. The light didn't follow for a while. Then, at the mouth of the cave, the water flashed bright blue, once, a small clean spark, like a hand waving.

*Thank you for the tour. We've decided to stay for a bit longer.*
*The cave is lovely once you get used to the cold. Ellie likes it best. She says the animals are her friends. She says they only glow when someone is watching, so she's been keeping them company.*
*Please tell the next family to bring a warm layer. And to ask the guide to count the seats before they leave.*
*Rosa and Ben, and Ellie.*
