When Jessica Thomson was shown the Somerton Man’s plaster bust, which was already publicised in photographs for the 1949 inquest, her apparent shock raised questions: was it authentic emotion, or a staged display straight from the tradecraft playbook?
Key Points
- The Scene: Jessica Thomson
appeared shocked, some thought she might faint when asked to view the
plaster bust of the Somerton Man.
- Prior Publicity: By then, the
1949 inquest had already been held. The bust had been presented in court,
and newspapers had published photographs of both the deceased and the bust
itself.
- Her Background: As a wartime
nurse, Thomson would have been familiar with death and trauma, making
fainting at a plaster cast seem unlikely on medical grounds alone.
- Possible Interpretations:
1.
Genuine Recognition: The stress of formal identification triggered an
authentic emotional reaction.
2.
Performance: Manuals from the SOE and CIA taught operatives to “affect
ignorance” or stage emotions to deflect suspicion. Her reaction could fit
that mould.
3.
A Blend: Real feelings, consciously or unconsciously shaped into a
display.
- Boxall’s Remark: Army officer
Alf Boxall later described her as “very courageous,” suggesting composure
under pressure rather than helpless surprise.
- Takeaway: Her behaviour was striking but ambiguous. The publicity surrounding the bust complicates claims of spontaneous shock, yet the reaction remains consistent with known espionage tradecraft.
The Bust
Room Reaction: Shock, Performance, or Something Else?
When Jessica
Thomson was escorted by police to view the plaster bust of the man found dead
on Somerton Beach, observers recalled her being visibly shaken — some even
thought she was about to faint. This moment remains one of the most scrutinised
events in the Somerton Man case, often cited as evidence that she knew the man.
Yet the context makes the reaction harder to interpret. If this was an act, whose benefit was it for? Why would she do that?
Prior Knowledge
By the time
Thomson was asked to see the bust, the 1949 inquest had already taken place.
The plaster cast had been created for that court, and contemporary newspapers
ran photographs of Detective Sergeant Leane carrying it into the hearing.
Alongside earlier press photographs of the deceased himself, Thomson would have
had ample opportunity to see both the man’s features and the bust’s likeness
well before stepping into the police viewing room.
That diminishes the argument that her reaction was the result of sudden, unexpected shock.
Interpreting
the Reaction
There are at
least three ways to frame what happened:
1.
Genuine Recognition
Jessica may have recognised the likeness and the emotional weight of being
asked to identify the man, formally and under official observation, overwhelmed
her. The difference between a newspaper photograph and a real, physical bust in
front of detectives is not trivial.
2.
An Act of Performance
Intelligence training manuals of the 1940s provide another possible lens. The
SOE’s How to Become a Spy advised agents to “affect ignorance”
when questioned, to appear dull or harmless rather than informed. Other
sections recommended feigned emotional outbursts to deflect suspicion.
Similarly, the CIA’s Manual of Trickery and Deception advised operatives
to appear “non-threatening” or even “dumb” to avoid drawing scrutiny. In this
light, Thomson’s apparent faintness could have been a performance: a staged
display to persuade police she was shocked and therefore uninvolved.
In other words, they were taught how to act their way through situations
3.
A Blend of Both
Human behaviour rarely fits neatly into one box. If Thomson did know the man,
she may have felt genuine distress but shaped her reaction deliberately to
guide how others perceived her — a blend of authenticity and strategy.
Boxall’s
Remark
Army lieutenant Alf Boxall, to whom Jessica had once given a copy of the Rubaiyat, later described her as “very courageous.” That choice of words is striking. He did not describe her as “innocent” or “surprised” but as “courageous”, language that resonates more with someone under pressure maintaining composure than with a civilian overwhelmed by shock.
The
Problem of Interpretation
Does this necessarily that she was an operative or that her response was consciously staged? Eyewitnesses themselves disagreed about how extreme her reaction really was,
and memory is fallible.
What the intelligence manuals demonstrate is not certainty but plausibility: that such displays of emotion were consistent with the tradecraft of the era. Given her medical background and prior public exposure to the man’s likeness, the “raw surprise” explanation is less convincing. But that still leaves open the possibility of genuine emotion, or a carefully shaped mix of both.
Takeaway:
Jessica Thomson’s reaction to the Somerton Man bust remains one of the most
enigmatic moments of the case. Her training as a nurse, the prior publicity of
photographs, and the bust’s courtroom presentation mean shock alone is
difficult to credit. Yet intelligence manuals show that feigned ignorance and
emotional displays were standard tools in espionage tradecraft. Whether
consciously deployed or not, her performance in that room fits patterns known
to operatives of her time — while still leaving space for the possibility of
genuine emotion.
Earlier this year I posted details of two infiltration operations carried out under the mantle of Australian Military Intelligence, two man, two different target organisations. It is possible that Jessica was such an operator trained to infiltrate not just a local subversive group but the activities of a much larger more menacing organisation, The Australian Communist Party.

Here are some thoughts for your consideration. We've mentioned how those involved in espionage of one kind or anther, learn how to act as part of their training. That applies whether they were Ãllegals' as in foreign agents or local agents, those who perhaps have been trained specifically to infiltrate suspect or subversive organisations. Here's a link to the post:

Have we discounted the possibility that Jessica was genuinely shocked because she did not recognize the bust, but had expected to - i.e. the bust was not the person she thought it would be?
ReplyDeleteHi, The short answer is yes, I have considered that and in the past I have thought that was the case. However having read wide and deep on the issue of interrogation in an espionage context and the role play/Legend that agentas adopt, on balance I think she was acting. My reasoning is straightforward, her physical behaviour was of a nervous and frightened young mother but it was only one person, Paul Lawson, who thought she might faint. The others, experienced Detectives did not say that. I spent many hours talking with Paul and he was an old school gentleman who had his fair share of empathy and would have been affected by Jessica's demeanour unlike the hard bitten detectives.
ReplyDeletePerhaps the most important influencing factor is the contrast between her physical demeanour and her quite consistent response of 'No' when asked if she had known the man show in the bust. She had also said that as it happened she had given a copy of the same book to an Army Lieutenant. That would have been Alf Boxall of course who she named at the time.
In a later meeting with Gerry Feltus he formed the opinion that she was being evasive.
The bottom line is that the inconsistencies won the day.
Thanks for the comment and I hope this helps
