Marta went through her grandfather's papers that weekend, with her parents' knowledge and help.
She found two things significant to Lena's investigation.
The first was a reply from the maritime museum, dated March 1979, two months after Alistair Fenn's letter. The reply was brief, from a junior archivist rather than the senior staff, and said that the Maren Castle records showed the vessel had been lost in the February 1932 storm and that the museum had no further information about the location of the wreck. It thanked Fenn for his detailed observations, which had been placed on file.
The reply did not acknowledge Thomas Fenn. It was possible the archivist had not noticed the surname connection, or had noticed and considered it a private matter. Either way, Alistair had received an official confirmation of what the records showed and nothing more.
The second thing was a notebook. Not the lighthouse log, which covered professional observations, but a personal notebook, smaller, with a soft brown cover. Marta had found it in a box of personal papers at the bottom of a wardrobe.
She brought both items to Lena on Sunday afternoon and they sat at the harbour wall again, in the August sunshine, and went through them together.
The notebook was not a daily diary. It was intermittent, written when there was something specific to record. The first entry was from 1971, the same year the grey vessel entries began in the lighthouse log.
June 1971. Saw the ship again this morning. I have seen it before, perhaps six times in the years since I came to this station, but always at the edge of visibility. Today it was closer. I could see the profile clearly. Castle class steam trawler, the kind my mother kept a photograph of on the mantelpiece when I was a child. She never talked about him. I know only that he went out on the Maren Castle in February 1932 and did not come back, and that I was two years old and have no memory of him at all.
Lena and Marta read this together.
I am not a superstitious person. I do not believe in ghosts or in ships that return from the dead.
What I see is light. The image of a ship made in light, still present in the air above this water, forty years after the light that formed it was produced. This is what I choose to believe, and it is the explanation that allows me to look at it without falling apart.
It is also, possibly, true.
They read the subsequent entries without speaking. Alistair Fenn's seven years of watching, in his own private words rather than the professional language of the lighthouse log. The same events, the same observations, but with the layer beneath them visible. A son who had grown up without his father, who had taken a job at the lighthouse where the ship had gone down and had spent seventeen years watching the water, and who had seen, repeatedly, something he had chosen to understand as an optical phenomenon because that was the explanation that let him continue to look.
The last personal notebook entry was from December 1978, the same month as the final grey vessel entry in the lighthouse log.
I wrote to the maritime museum in January. They replied in March. The Maren Castle was lost in the February 1932 storm. No wreck located. All crew lost. Thomas Fenn, age 24.
I have his name in official writing now. I have the record that he existed and that he went down in that storm. I have seven years of my own observations. I do not know if the image I saw was the Maren Castle specifically. I believe it was. I cannot prove it.
I think I have been looking for him for a long time without fully knowing it. I think I found what I was going to find. The light of that ship, still present in the atmosphere above these waters. Still visible, under specific conditions, to someone who knew how to look.
I do not think I need to keep looking now.
Marta folded the notebook closed carefully. She held it for a moment without speaking.
Lena looked at the water, which was blue and bright in the August sun, entirely peaceful, entirely itself.
She thought: a man spent seventeen years at a lighthouse watching for a ship that had taken his father before he could remember him. He found the best explanation available to him, one that was both scientific and true enough to be bearable. He wrote it down in a professional log and a private notebook. He wrote to a museum and received a name in official writing. Then he stopped.
She thought: the lighthouse log ended up in a box outside the post office, forty years later, and a fourteen-year-old on holiday found it and followed the thread.
She thought: Alistair Fenn wrote, in his professional log, that a log should not omit observations because they were inconvenient to explain. He had kept the record, and the record had eventually found its way to someone who read it with the attention it deserved.
She thought that mattered. She was not entirely sure why it mattered, but the feeling of its mattering was strong and clear.
