Followed Everywhere
North Pacific, approaching the date line · 40.0° N, 175.0° E

After yesterday, today felt like the ship exhaling.
Calm sea, broken cloud, a light breeze from the west. The kind of day where nothing happens, and you are grateful for it.
The investigation
I had decided to solve the mystery of how Container gets into my cabin. I closed the door last night and checked it. I checked the porthole, which does not open. I examined the ventilation grille, which would not admit anything larger than a determined thought.
At six fifteen I woke up facing the ceiling. Container was sitting on my chest, face lowered, watching me with polite concern.
I asked Marco at breakfast. Marco has been on this ship longer than most and knows everything. He thought about it carefully, then said, "She is a ship's cat," as if that explained everything, which I suspect to him it did.
Tiny's theory is that she does not get in at all, she simply has always been in, and only becomes visible at dawn. I said that was unscientific. He said so was my Mazda's turbo installation and that had worked out fine.
The long walk
I walked my usual few miles along the walkways this afternoon, and Container came with me for every metre. Two steps behind. Stopping when I stopped. When I leant on the rail to look at the sea, she sat beside my boot and looked at the sea too, which was more companionable than I would like to admit.
At one point I turned round suddenly to see what she would do. She sat down and looked at a container as though she had always meant to examine it.
Evening
A small celebration tonight. We crossed the date line at some point in the small hours, or we will, depending on which clock you trust, and there is apparently a tradition, which I am being told about in fragments and with suspicious smiles. I have been warned I may live a particular day twice. I have decided not to ask which.
Elena made a lemon tart. I ate mine in full, without sharing, which drew a round of applause I did not entirely appreciate.
Then I went back to the cabin, closed the door, and turned off the light.
I will let you know where she is in the morning. I think we both already know.
