Dear Corporate Citizen!


After thirty years of international business / industry experience, we have chosen to concentrate and develop our private / finance detective firm, assisting companies, individuals and organisations – with an emphasis on commerce and finance – in Scandinavia and northeast Europe, also into the Americas, southwest Europe, Africa and Asia.


Winston Churchill quipped that “America will do the right thing – once it has exhausted all other opportunities”; and it is wildly dangerous to assume that Russia’s future will simply be an extrapolition of its present, when even Russians say it is impossible to predict anything in their country – even the past; and the eurozone is confronted with a crisis of not just labor costs and prices – but of culture and work ethics, despite some of its members having pockets as deep as the Mariana Trench.


Surely politicians recognize that entrepreneurs accept levels of risk that no rational person would contemplate, albeit most people want one thing more than even love – peace of mind.


Decline is not a condition, but a choice and instead of letting out a cri du coeur and eating humble pie, we would like to see finance less proud and industry more secure.


The first imperative must be to restore security; without security, running a business successfully, is like having “turtle soup without the turtle”.


In extremis, amid global financial and trade conflicts, a self-sufficient America might see things occur that have not occurred before, although they have occurred in Europe, albeit [America] might confound the unusual with the abstruse.


Being able to develop Walhallen Finance / Private Detectives into a truly integrated, global and robustly competent group is a privilege, and this mainly due to having the opportunity of gathering the most talented private investigators / detectives available: from Russia-Ukraine-Germany-Sweden-Norway-France-China-USA-Kenya and Brazil.


Our private detectives, from armed forces-intelligence services-business-academia, will convincingly add value to customers and clients with positive terra firma ambitions for years ahead – and, not only in their own countries, albeit worldwide, which is our factual modus vivendi: A Global Private Finance and Business Detective, specialising in industrial undercover work and counterindustrial espionage, including advanced Technical Surveillance CounterMeasures (TSCM) and computer forensics.


As noted in a Walhallen Intelligence / Private Detective Estimate Report: "The hostile intelligence threat to corporate / company computer systems is magnified by the enormous growth in the number and power of computers, the vast amount of data contained in them, as well as dismal Internet security measures. Computers multiply hugely the information to which a single individual may obtain access, hence the vast risk. For businesses, as well as for private individuals, we design, customise and implement encryption communications and storage software; 100% unbreakable.  


Rise of the incognito Internet does not imply that the maxim of "nothing to hide, nothing to fear" should apply to Internet security... The peculiar psychology of code-breaking often involves one genius trying to work out what another genius has done, at times resulting in the most appalling carnage. To break a code - or the most abstruse cryptogram, even for an experienced private detective / private investigator - is to extend a hand to grasp the sky and hope to catch a bird.


“Trade follows the flag,” declared Cecil Rhodes, and as globalization forces many companies to move strategic assets abroad, even to another continent – terra nullius / no man’s land, there is a need to be en garde, if not actually aux armes. However, the Mafia - the Mob - the Cosa Nostra - the Camorra - the 'Ndrangheta - the Yakuza, and other criminal groups are cunning, no more.


Formidable as they might be, Mafia button-men do not have the intelligence training of a professional private detective/private investigator, and are tabby cats next to panthers in this particular jungle. As private detective-s/private investigator-s we combat these daggers with inflexible determination, however, given the Underworld's predilection for deception, unique situations present us with some strange bedfellows.


In contacts with these, and other monstra horrendum - before contacting private detectives / private investigators - I would paraphrase Theodore Roosevelt: "Speak softly, but carry a big stick." Often, when you want adult behaviour, treat people like babies; while we believe humans are rational, their behaviour is constantly the opposite.

To be beaten by one of your own is not as bad as be beaten by a foreign one, however, and roaring like a mouse, fighting like a flea singing “Give me your arm, old toad; Help me down Cemetary Road” would make us appear useful idiots. A proper attitude can turn a burden to a blessing, a trial to a triumph. As Johann Wolfgang von Goethe would express it: "Unglück ist auch gut."

Being part of a diaspora in dire straits, one can be comfortable imagining existing alongside an independent judiciary rather than in a smash’n grab society – Raubwirtschaft. However, possession is nine tenths of the law, and with foreign officials reasoning – “I am with my brother against a cousin, and with my cousin against a stranger”, many bona fide intentions will be jeopardized.


Growth and developing economies hide a thousand sins, and with the cruel clarity afforded by distance, you might realize you have interests rather than friends. For example, the recent murder of a middle-aged (41 year-old) British businessman – supposedly Aston Martin’s representative in Beijing – and a close friend of one of China’s fourteen most powerful politicians (Bo Xilai-now imprisoned), adds an international dimension to this country’s most serious political upheaval in two decades, and exposes uncomfortable truths about how business and politics are conducted in the world’s second-largest economy.


In this area of the world your enemy's enemy is probably your enemy too. A friendly feeling does not equalize a friendly intent; alas, often au contraire, a hostile intent blends very well with a friendly feeling.


Always use international, experienced private detective-s / private investigator-s in developing / transition economy countries when you need fast, accurate and reliable CCCI [Control-Command-Communication-Intelligence]. There are effective and efficient bureaus beyond Walhallen - that we can recommend - for a great many lesser undertakings.


Too tough a bargaining for low private detective / private investigator retainer fees could cost you dearly, indeed - nota bene! - more precious things. Free armchair advice is always rich and plentiful.


The verb corrumpere means destroy in Latin, and having seen that [corruption], as plaintiffs’ private detectives in commercial and criminal courts numerous times, we agreed to co-found The International Intelligence Institute of Commerce (www.wiiic.org). The Principal Investigator of WIIIC welcomes any information of corruption, grand thefts, miscarriages of justice etc. “Shame and silence are cousins” – right?


The Institute will be able to provide unbiased Independent Business Resolutions’ Schemes, lightening the burden of 

courts-prosecutors-lawyers-accountants, who often miss the “red flags” that a private detective detects, as well as carry out Forensic Audits and Impairment Tests; and this in addition to hosting an academic research and education group focusing on Intellectual Property and Patented Technology.


The Romans used to assess situations metaphorically, e g: Cum catapultae proscripta erunt, tum soli proscript catapultas habebunt – "When catapults are outlawed, only outlaws will have catapults". Their reasoning implies “rules replace common sense and reason”.


In a fair and just society, with archaic European and American legal practices – often hiding behind procedure – and an international institutional machinery that grinds along at a pace that would shame snails, preparedness is the key to success and victory. Western governments also often “piggy-back” on existing national investigations rather than undertake their own probes, creating “double jeopardy” by triggering separate prosecutions of the same case in different jurisdictions.


You learn in my business there aren't any rules, whether in corporate or business fraud cases, internet security or computer forensics cases, divorce or alimony cases; you are dealing with infinitely variable factors - the human heart and mind. My role is not to have a formula, and not to take one single thing for granted. It is my business to know what other people do not know ... in particular regarding


-corporate and international fraud, proof and accounting documentation, court preparations, taxes/VAT-    calculations, general surveillance and personal protection.


-internet security, computer forensics and cryptography (the latter meaning "secret writing" in Greek).


-matrimonial affairs - divorce, child custody, infidelity and alimony.


There are truths which are not for all men, nor for all times; albeit, to a great mind nothing is little, and the humbler of our private detective / private investigator clients are usually the more interesting. Characterizing sought-after information as elementary does not, of course, imply that it is easy to get or even that it is a simple matter.


Modern business and private lives are complex, and many sang-froid judges realize not even they are equipped to parse the facts; proximity to real power, though, is intoxicating – and misplaced pride melts away. Retaining an International Private Detective should be a “game-changer” – levelling the playing field; not looking sheepish, or even hare-brained – without proof or evidence.


Throughout college- and university, I trained and served as an air artillery aviator, worked as a shop/department store detective, ordinary guard, heavily armed body-guard for Ambassadors / Charge d’Affaires from Germany, England, Yugoslavia, the U.S., Iran and Russia, as well as within the Swedish Penitentiary / Prison Authority; later as chairman of an authorized guard-guard and patrol company, and as an international legal administrator, approved by Swedish courts, in Poland, Russia and Ukraine.


My partners and associates may on occasion exceed me in experience and ability, albeit, the private detective team courage d'esprit will always be decisive and of paramount importance.


A crisis is a terrible thing to waste – and should worse come to worse – it’s not part of private detectives’ job description to add mirth to the party, but provide and demonstrate solid, tangible, admissible evidence and stark proof....


Thank you for reading my introduction.


Yours sincerely,

Claes Reinhold Ekman
