How the world of private investigation took shape — from ancient times to the Armenian reality. People usually look for the crime. Detectives look for the details. Years go by and the world changes at dizzying speed: states rise and fall, technology rewrites the rules of life, wars redraw borders, the world becomes digital and unpredictable, and human relationships grow ever more complex and ambiguous. But one thing remains unchanged, as the deepest trait of human nature: someone is always trying to hide something — a lie or a secret, a mistake, pain or deceit — and someone else is trying to find and understand the truth. It is in this eternal confrontation that the detective is born. Not as a movie hero or a “good guy” with a gun, but as someone who has learned to see what others overlook. The profession is built not on force or violence, but on the psychology of observation, deep analysis and an understanding of the truth. Today you can learn everything about a person without ever meeting them, follow them without coming physically close, and uncover an entire life from a single digital trace.
The more complex and digital the world becomes, the more indispensable is the person who can see invisible connections, contradictions and hidden patterns. The detective becomes not just an investigator but a specialist who understands the deep processes of the times and works in the security market.
The first “detectives” — long before the word existed
Many people think the detective profession began in the 19th century. In fact, its roots go back thousands of years — to ancient Rome, Sumer and Egypt. Back then the state had no professional police, so the rich and powerful hired private guards, informants and trackers to solve thefts, watch political opponents, hunt down fugitives or learn their rivals’ secrets. In ancient Egypt, tomb guards and private watchmen acted as a “private” force. In ancient Rome, the vigiles (firefighter-watchmen) arrested thieves and runaway slaves, while wealthy citizens used freedmen as private investigators — to find debtors, watch unfaithful spouses or expose political conspiracies. This shows that private investigation is almost as old as humanity itself. It was born not of the state, but of mistrust and the need for security. The wealthy did not trust the authorities and built their own “intelligence” networks. This was the prototype of the modern private detective, where information is power and a secret is a commodity.
London and the first professional investigators
In 1749, the London writer and magistrate Henry Fielding founded the Bow Street Runners, London’s first professional police and detective force. They were not ordinary watchmen: they were paid and worked in an organised, methodical way — tracking down criminals, gathering information, conducting surveillance and analysing information on the spot. Until then, solving crimes in England had largely been left to ordinary citizens. The Bow Street Runners changed the whole approach, turning investigation into a professional and analytical discipline. It was the first step towards modern detective thinking: a good investigator must not only be strong, but also able to think and connect the dots.
Eugène Vidocq: the birth of the “criminal-turned-detective” mindset
If the London investigators created a system, Eugène François Vidocq created modern detective thinking. His life reads like a novel: a criminal, a fugitive and a forger who went on to become a symbol of the police. In 1811 he founded the Sûreté, France’s first criminal investigation bureau, and in 1833 the world’s first officially recognised private detective agency. Vidocq understood what 19th-century police did not: force alone is not enough to catch a criminal. You have to understand the person — the way they think, their fears, their habits. He introduced revolutionary methods: covert surveillance, behavioural analysis, criminal record files and the first elements of ballistics. He was the first to use plaster casts of footprints and handwriting analysis to identify offenders, and he became the father of modern criminology. But Vidocq’s most important innovation was philosophical: a former criminal turned detective showed that the line between truth and lies is blurred. His memoirs inspired Balzac, Victor Hugo and Edgar Allan Poe. A real detective gave birth to literary heroes, and literature turned those images back into reality.
Sherlock Holmes: when the detective became a legend of intellect
Arthur Conan Doyle’s Sherlock Holmes turned the detective into a global cultural phenomenon. “People usually see, but do not observe” — this idea became the philosophy of an entire genre. Nothing in Holmes’s world was accidental: the colour of ash, mud on a boot, a crease in a sleeve, the choice of a word. His strength was the art of thinking — seeing structure in chaos. Today open-source intelligence (OSINT) specialists, digital investigators and corporate analysts work on exactly this principle: finding, among thousands of seemingly meaningless details, the one that changes the whole picture.
Allan Pinkerton: when the detective became a system
In 1850, Allan Pinkerton founded the Pinkerton National Detective Agency, America’s first large private investigative organisation, which still operates today. Pinkerton saw the future: wars would be fought over information. He built an intelligence ecosystem — databases, a network of agents and analytical archives. The famous “open eye” emblem and the motto “We Never Sleep” became the face of the profession, and this is where the expression “private eye” comes from. He was also the first to hire a female detective. Today’s corporate investigations and risk assessment trace their roots back to Pinkerton.
Maigret and Poirot: the return of the human
Georges Simenon’s Commissaire Maigret and Agatha Christie’s Hercule Poirot brought human depth back to the genre. Maigret understood that crimes are often born not of malice but of loneliness, humiliation or wounded dignity. Poirot believed in the “little grey cells” — in the details that give a lie away: the position of a body, a word that was spoken. Good modern detectives work at the intersection of all these schools, combining psychology, drama and a systematic approach.
Armenia and the birth of a new detective
The private detective did not exist in the Soviet system. The truth was a state monopoly, and the profession lived only in books and films. After the collapse of the USSR, the stereotypes about private investigation began to crumble too. Detective agencies appeared in Russia and many other former Soviet countries. Until 2021, detective activity in Armenia was considered illegal and was prohibited. On 3 August 2021, Gabrielyan & Partners Detective Bureau was founded — the first officially registered and still the only organisation in Armenia engaged in private detective work. In 5 years of operation, all the stereotypes about detectives in Armenia were broken, and society saw what a real detective is: not just “someone who follows people”, but an information analyst, a risk assessor, a fighter against crime and someone who helps people. It was not just a business but the foundation of an entire culture in Armenia. For the first time, open-source intelligence, due diligence, business security and international investigations were discussed openly. The detective stepped out of the shadows and became public, combining old methods with new tools.
The detective as a guardian of time
A modern detective does more than solve crimes. A detective protects time. Every case is a story about society. When a partner cheats, when a person lives for years under a false identity, when you are deceived in the name of love — that is a security crisis. The biggest problem of our age is that an abundance of information does not replace the truth. The detective tries to reconstruct the real picture from data, silence and human behaviour. Sometimes late, sometimes painfully, but always the real truth.

Editor’s note: the stories published in the series “The Detective Investigates” were based on real cases investigated by Gabrielyan & Partners Detective Bureau, Armenia’s only officially registered private detective organisation, and were presented by Hayk Gabrielyan, Chairman of the Association of Private Detectives of Armenia. As of today, we are pausing the series for a while.
Our detective author is writing a book, and Aravot’s legal page plans to start a new series with him in September.
