Somerton Man
Two words in my pocket and the last beach
▲ Cover of the incident – Unfolding the records
On December 1, 1948, a neatly dressed man was found dead on Somerton Beach in Adelaide, Australia. Hidden in a small pocket was a piece of paper with ‘Tamám Shud’ printed on it.
My conclusion is this: It is very likely that the Somerton Man was Charles Webb, and his reason for coming to Adelaide is more likely to be linked to personal relationships rather than espionage. However, since there is no evidence to confirm the specific poison and the author of the book, the manner of death cannot be determined.
Prologue: The night that broke records
When I laid out the case data on my desk, the first thing I noticed was not the correct answer but an imbalance. Some scenes were overly clear, and some time periods were completely blank. People try to explain the entire incident by focusing on one clear scene, but I instead marked the blank section first. Mysteries can arise because there are many clues, but they can also arise because the distance between clues is too great.
Autopsy records show that the man bought a ticket at Adelaide Station the day before and traveled to the beach by bus. In 2022, a team of researchers announced that it was very likely that he was Carl ‘Charles’ Webb, but as of this writing, the formal autopsy process remains in its final stages.
I did not view this incident as confirming an already known conclusion. The records were arranged chronologically, the movement paths of objects were drawn separately, and sightings and interpretations were indicated in different colors. The most popular explanations were then deliberately reviewed last. Because when you first read a famous hypothesis, all the clues seem to exist for that hypothesis.

Case Files: What I Could Believe
| number | confirmed record | current reliability |
|---|---|---|
| 1 | The man was found without identification and name tags had been removed from several of his clothing. | high |
| 2 | From the small pocket of my pants came a piece of paper called ‘Tamam Shud’, the last part of the Rubaiyat. | high |
| 3 | The version of the book connected to the sculpture had a string of capital letters and a phone number written on it. | middle |
| 4 | The suitcase and clothing had T. Keane markings on them, and the cause of death was not determined by a specific substance. | middle |
Although the identity candidates have been greatly narrowed, the purpose of the final movement, cause of death, and the relationship between the letter string in the book and the phone number have not yet been confirmed.
The sentence ‘It is not explained’ is not the same as the sentence ‘It is supernatural’ or ‘Someone intended it’. I didn't use the blank space as evidence.
▲ Timeline – Flow before and after the event
Reconstructing the Scene: Finally, a Certain Point
I changed the location where the incident took place to the actual route rather than the stage in my head. We divided the starting point, final confirmation point, and discovery location and calculated the time needed in between. In the process, several later dramatic depictions were omitted. Instead, the recorded sounds, weather, means of transportation, and locations of objects came to the fore. The novelistic atmosphere arose from the very texture of the facts. There was no need to add unidentified secret passageways or nameless accomplices.
When reconstructing the last scene, I did not determine the character's feelings. The same behavior can be caused by fear, planning, mistake, or fatigue. So, I wrote down the actions first and left the emotions to the extent possible. Thanks to this principle, events became less flashy but more concrete.
Clue 1. The man was found without any identification and the name tags on several of his clothes had been removed.
I placed this sentence in the middle of the case record and checked the tense first. It was differentiated from who observed it and when, and whether it was written down on the spot or added from memory later. The older the clues to an unsolved case, the more seamless the story becomes. However, what is needed in an investigation is not smoothness but provenance. The moment I discerned whether this clue was a direct observation, a trace left by an object, or someone's interpretation, the outline of the incident changed.
If we leave out this clue, a one-way conclusion seems very plausible. But I immediately tried it against the next record: “From a small pocket of my pants came a piece of paper called ‘Tamam Shud’, the last part of the Rubaiyat.” If the two do not naturally coexist in the same explanation, the explanation is still just a story. In particular, a hypothesis that does not pass the question, “Do unused train tickets and bus movements mean that the original destination has changed?” will ignore the rest of the record instead of explaining one clue.
So I created three spaces in my case notes. The first is a confirmed fact, the second is an inference that goes one step further from the facts, and the third is a possibility that cannot be selected without additional evidence. This clue is a mixture of parts that are close to the first space and parts that stay in the second space. I didn't erase that boundary. Leaving boundaries is the only way to modify your reasoning later when new records emerge.

Clue 2. A piece of paper called ‘Tamam Shud’ from the last part of the Rubaiyat was found in the small pocket of the pants.
I placed this sentence in the middle of the case record and checked the tense first. It was differentiated from who observed it and when, and whether it was written down on the spot or added from memory later. The older the clues to an unsolved case, the more seamless the story becomes. However, what is needed in an investigation is not smoothness but provenance.

If we leave out this clue, a one-way conclusion seems very plausible. However, I immediately tried to match it with the next record, “The version of the book connected to the sculpture had a string of capital letters and a phone number written on it.” If the two do not naturally coexist in the same explanation, the explanation is still just a story. In particular, a hypothesis that does not pass the question “Is the piece of paper the last sentence left by oneself or is it part of a book left by chance?” ends up ignoring the rest of the record instead of explaining one clue.
So I created three spaces in my case notes. The first is a confirmed fact, the second is an inference that goes one step further from the facts, and the third is a possibility that cannot be selected without additional evidence. This clue is a mixture of parts that are close to the first space and parts that stay in the second space. I didn't erase that boundary.

▲ Key Clue 2 — Pieces that do not fit together
Clue 3. The version of the book connected to the sculpture had a string of capital letters and a phone number written on it.
I placed this sentence in the middle of the case record and checked the tense first. It was differentiated from who observed it and when, and whether it was written down on the spot or added from memory later. The older the clues to an unsolved case, the more seamless the story becomes. However, what is needed in an investigation is not smoothness but provenance.

In particular, a hypothesis that does not pass the question, “If the identity is confirmed as Charles Webb, will the book and cause of death be explained?” will ignore the remaining records instead of explaining one clue.
So I created three spaces in my case notes. The first is a confirmed fact, the second is an inference that goes one step further from the facts, and the third is a possibility that cannot be selected without additional evidence. This clue is a mixture of parts that are close to the first space and parts that stay in the second space. I didn't erase that boundary. Leaving boundaries is the only way to modify your reasoning later when new records emerge.

put three hypotheses on the same scale
Hypotheses were not evaluated in fancy sentences. We wrote down the number of explanatory clues, the number of new assumptions required, and the degree to which they can withstand contrary evidence. Even if one clue is completely explained, if the remaining three clues have to be discarded, it is not a good hypothesis.
Hypothesis A. An explanation that he hid his identity and chose his own end during a personal crisis.
The advantage of this explanation is that it makes relatively few assumptions about the clues, “The man was found without identification and name tags had been removed from several of his clothing.” I first assumed that this hypothesis was true and re-traced the event from beginning to end. Each sentence linked where and what the character saw, what judgment he made, and then moved to the next location. There was always a hidden assumption at the point where the connection was lost.
The biggest weakness is that it does not sufficiently explain that “the edition of the book connected to the sculpture had capital letter strings and phone numbers written on it.” If you keep adding exceptions to your hypothesis, you can explain anything, but such an explanation predicts nothing. I lowered the score of the hypothesis the moment there were more than two exceptions. Conversely, scores were increased only when two independent clues pointed in the same direction.
In the end, this hypothesis cannot be completely discarded, but it cannot be taken as a conclusion either. If you read the incident like a novel, the blank spaces will be filled in naturally. If you read it like an investigation record, the blank spaces remain. I chose the latter. Even if the blank space left is inconvenient, that inconvenience protects the scope of what the evidence can say.
Hypothesis B. Explanation that after the intervention of a third party, the scene remained as if it were a spontaneous death.
The advantage of this explanation is that it makes relatively few assumptions about the clue: “From a small pocket of the trousers came a piece of paper called ‘Tamam Shud’, the last part of the Rubaiyat.” I first assumed that this hypothesis was true and re-traced the event from beginning to end. Each sentence linked where and what the character saw, what judgment he made, and then moved to the next location. There was always a hidden assumption at the point where the connection was lost.

Hypothesis C. Explanation that the book and the string of letters are traces of espionage activities.
The advantage of this explanation is that it accepts the clue “The edition of the book connected to the sculpture had a string of capital letters and a phone number written on it” with relatively few assumptions. I first assumed that this hypothesis was true and re-traced the event from beginning to end. Each sentence linked where and what the character saw, what judgment he made, and then moved to the next location. There was always a hidden assumption at the point where the connection was lost.

▲ Comparison of hypotheses – explanatory power and gaps
Conclusions I threw away
When I began my investigation, I too was drawn to the most popular explanation. It summed up events in one sentence and gave intention to every object. But when the data was collated, the explanation required a new coincidence for every blank space. I erased that conclusion and started again. Good reasoning is less about adding things and more about removing unnecessary assumptions.
I did not tie the meaning of identity, death, and books into one answer. Separating the three layers, the espionage hypothesis had a strong atmosphere but the weakest independent physical evidence, and the personal crisis hypothesis explained the known circumstances of life and pieces of paper but did not completely explain the book's travel route.
In particular, details repeated in later testimonies and on the Internet were separated from the original records. Just because the same sentence appears in multiple places does not mean there are multiple independent sources. First, we checked the possibility that a single incorrect sentence was duplicated. After going through this process, the size of the case decreased, but the weight of the remaining clues actually increased.
▲ Counterevidence check — the conclusion I discarded
Final Reason: What I arrived at
My conclusion is this: It is very likely that the Somerton Man was Charles Webb, and his reason for coming to Adelaide is more likely to be linked to personal relationships rather than espionage. However, since there is no evidence to confirm the specific poison and the author of the book, the manner of death cannot be determined.
This conclusion is not a completely definitive ruling. This is a direction that requires the fewest assumptions and simultaneously explains the most clues within the currently available records. It may be revised as new physical evidence emerges. However, it is also clear that the conclusion may change depending on what comes out. Reliable original records, verifiable forensic data, and independent evidence directly linking objects and people are needed.
I do not write that the case is closed. Instead, write down how far you can close it. That boundary is the result of this investigation. The fun of mystery is not that anything is possible. The goal is to find out which of the possible explanations can be discarded.
▲ Final judgment – explanation that requires the fewest assumptions
Additional Investigation Records 1. Redraw the timeline
At dawn, I opened the case sheet again. This time, the conclusion was obscured, leaving only the record, “The man was found without an identification card, and name tags on several clothing items had been removed.” Even events you thought you already knew reveal a completely different picture if you erase the conclusion. I lined up the locations and times and wrote down the minimum travel time. The gaps between records were not filled by imagination but were marked with empty squares. As the square grew, the reliability of the hypothesis explaining that section decreased.
Above that, I put the hypothesis that “the explanation is that he hid his identity and chose his own end in the midst of a personal crisis.” At first everything seemed to fall into place. However, when we substituted the question, “Do unused train tickets and bus trips mean that the original destination has changed,” a weak part of the explanation was revealed. Hypotheses must withstand questioning. If you keep bringing in new characters or coincidences to avoid questions, from that moment on, it becomes creation rather than reasoning. I used my creative sense only for the mood of the sentence and did not place it in the place of facts.
The results I got from this section are neither a definitive name for the culprit nor a complete decipherment. Instead, it became clear which explanations required fewer assumptions and which ones flipped when new discoveries were made. Even if the case cannot be closed, it is possible to narrow the scope of the investigation. This record is intended to leave behind that narrowed boundary.
Additional investigation record 2. The missing link
At dawn, I opened the case sheet again.

However, when we substituted the question, “Is the piece of paper the last sentence left by oneself or a part of the book that was accidentally left behind?” a weak part of the explanation was revealed. Hypotheses must withstand questioning. If you keep bringing in new characters or coincidences to avoid questions, from that moment on, it becomes creation rather than reasoning.
