The Fish Who Knew Too Much

Swift was the fastest fish in the entire postal service. This was not a small thing. The ocean postal service covered: Four oceans. Seventeen seas. One extremely opinionated lake that insisted on being included. And the deep dark trench that nobody liked delivering to but everyone agreed needed mail as much as anyone.

Swift had delivered: Love letters. Angry letters. Letters that were love letters disguised as angry letters which were the most common kind. Bills. Birthday greetings. One extremely long apology from a whale that took three trips to deliver completely. And once a letter containing nothing but a single pressed flower that made the recipient sit very still for a very long time.

Swift did not read the letters. This was the rule. The only rule. The rule that held the entire postal service together like a knot in a current. You carry. You deliver. You don't read.

Then came the letter.

It arrived at the sorting coral on a Thursday morning. Unremarkable envelope. Standard sea-paper. Addressed in ordinary ink. Except — it was heavy. Not heavy like a thick letter. Heavy like something that didn't want to be carried. Heavy like a stone that had made a decision.

Swift picked it up. Swift's fins dipped immediately. Swift swam. Swift dipped further.

By the second reef Swift was swimming sideways. By the third Swift was closer to the bottom than the surface. By the kelp forest Swift was practically dragging along the sand which was both undignified and extremely unusual for the fastest fish in the postal service.

Swift stopped. Looked at the letter. The letter looked back. Heavy and sealed and absolutely not helping.

The address said: The Oldest Turtle. The Place Where The Warm Current Ends. You'll Know It When You Get There.

Swift had delivered to The Oldest Turtle before. The Oldest Turtle had been alive since before the coral was coral. The Oldest Turtle had seen everything twice and found it mostly amusing.

Swift swam on. Sideways. Slowly. Sinking slightly with every stroke.

At the sunken ship a passing octopus looked at Swift with all eight arms worth of concern. "You're very low," said the octopus. "I'm aware," said Swift. "Heavy post?" "Extremely." The octopus looked at the letter. Then swam away quite quickly which was interesting.

At the cold current crossing a jellyfish drifted past. "You're dragging," said the jellyfish. "Thank you," said Swift. The jellyfish drifted on. Unhelpfully. The way jellyfish do.

By the time Swift reached The Place Where The Warm Current Ends Swift was swimming entirely along the ocean floor fins scraping sand nose pointed down the letter held above like a flag of considerable difficulty.

The Oldest Turtle was there. Of course she was. She was always there. She had been there since before there was a there to be at. She was enormous. And still. And looked at Swift arriving along the ocean floor with the expression of someone who had been expecting this for some time.

"The letter," said Swift. Breathing hard. Which fish don't usually do. "Is very heavy." "Yes," said The Oldest Turtle. "What's in it?" The Oldest Turtle was quiet for a moment. "Everything I should have said," she said, "to everyone I didn't say it to. In time."

Swift put the letter down. It sat on the sand between them heavy and sealed and full of all the things that don't get said until they are too heavy to carry anymore.

"Who's it addressed to?" said Swift. The Oldest Turtle looked at the envelope. "Myself," she said. "Forty years ago."

Swift looked at the letter. Then at The Oldest Turtle. "I can't deliver that," said Swift quietly. "I know," said The Oldest Turtle. "Then why send it?"

The Oldest Turtle looked at the ocean. All four of them. Simultaneously. The way very old turtles can. "Because," she said, "some things need to be written down and carried somewhere before you can put them down."

Swift looked at the letter on the sand. It was still heavy. But it was down.

"What do I do with it?" said Swift. The Oldest Turtle settled deeper into the sand. "Leave it," she said. "The ocean knows what to do with things that need to rest."

Swift left it. Turned. Swam back. Without the letter Swift was fast again. Fins level. Current-quick. The fastest fish in the postal service.

But something had changed. Not a big something. A small one. The kind that happens when you carry something heavy long enough to understand why it was heavy.

Swift delivered seven more letters before sundown. A love letter. Two bills. One angry letter that was probably a love letter. A birthday greeting. One pressed flower going to someone who would sit very still for a very long time.

Swift carried each one carefully. The way you carry things when you know what weight can mean.

Behind them on the floor of the place where the warm current ends — the letter settled into the sand. The ocean moved over it. Around it. Through it. Doing what oceans do with things that need to rest.
