Sooo i was bored and thought about this case once more and I have theories and i don't know if they're stupid or helpful but hear this
(Sorry if my english is not that great as it's not my first language)
according to me and the history
my first primary suspect will be the
cabinet secretary as they are the one getting about the info of the cases by Scotland yard
then another primary suspect will be the people close to Frederick Abberline or Donald Swanson as they can slip in and get an idea
and another suspect can be a divorced viscount or a viscount with a dead wife
Reason
Cabinet secretary: In 1888 London, it was actually a well-known practice called "slumming." Wealthy aristocrats and politicians from the rich West End would frequently put on old, rugged clothes and travel into the poor East End (Whitechapel) out of curiosity, or to visit underground clubs. Because of this, it is entirely possible that a high-ranking official could walk the dark alleys of Whitechapel without anyone realizing they were a powerful government figure.
The reason why I also choose a viscount and not a Prince, Duke, Marquess or an Earl is bc of the fact that a prince is surrounded by butler and maids who can easily confess when threatened plus the palece might be having record of when and how he left a Duke and Marquess are also are mostly surrounded by public and the fear of being betrayed by a butler or maid and risk of loosing their tittle and same goes with a earl but a viscount on the other hand is almost forgotten or not surrounded by the public eye plus they are rarely confronted
In simple words
The High Nobility (Princes, Dukes, Earls): Their households were massive. A Duke or Earl would have a house steward, a valet who dressed him every day, carriage drivers, footmen, and dozens of maids. If an Earl tried to sneak out at 2:00 AM covered in blood, his valet or the night-watch footman would immediately notice. The risk of blackmail or betrayal was massive.
The Viscount Rank: As a Viscount (which sits lower on the peerage ladder), an aristocrat would still be incredibly wealthy and have access to the finest education and surgical tools. However, their households were much smaller and less scrutinized by the public eye. They could easily maintain a small townhouse in London with minimal staff, or simply tell their few servants not to disturb them, allowing them to slip out unnoticed. They had the wealth of the upper class, but the anonymity of a regular citizen.
And the people close to
Donald Swanson and Frederick Abberline
can be the people like their wife
Or
a close friend or
noble friend or
any family member/doctor
So
The History: Frederick Abberline was married to Emma Abberline, and Donald Swanson was married to Julia Swanson. Both wives were highly respected, lived quiet domestic lives, and supported their husbands through the extreme stress of the 1888 manhunt.
The Profile: If a killer was close to the wives—perhaps a trusted family doctor, a cousin, or a close friend who visited their homes—they could easily ask casual questions like, "How is Frederick handling the case? Is he close to catching the monster?" The wives, speaking naturally out of worry for their husbands, might drop crucial details about police exhaustion or secret patrol locations without ever realizing they were feeding information to the killer.
The History: Inspector Abberline and Chief Inspector Swanson frequently had to interact with wealthy patrons, politicians, and high-ranking members of Victorian society who were fascinated by the case or demanding updates.
The Profile: A wealthy Viscount who befriended Abberline under the guise of "wanting to help the police" or offering funding to the investigation would have a perfect cover. They could sit down with the detectives for a drink, listen to them vent about the case, and pick up top-secret operational details. Then, using the disguise techniques, that same nobleman could slip into Whitechapel completely prepared.
The History: Donald Swanson’s family circle actually included people with medical backgrounds (his own son later became a doctor). Because the Ripper murders required anatomical knowledge, historians have always looked closely at doctors associated with the police.
The Profile: A family member or close friend who was a surgeon or medical student would have access to the exact tools used in the crimes. If they were close to Swanson or Abberline, they could hang out at the precinct or the detectives' homes, casually looking at the desk where crime scene photos and autopsy reports were laid out.
And the reason why I chose the divorce man or a Widower man is because we are humans and jack the ripper might also did his actions based on emotions. A man grieving a dead wife or bitter over a divorce might have had the psychological motive or rage that fits the brutal nature of the crimes.
Plus grief and anger can turn anyone into a monster
If we look into the case it can be more like animes like
Death note
Moriarty the patriot
And
Black butler
