Still, the 34-year-old son of the man who founded Kroll Associates, who works under his father as managing director of global business development and strategy of the company's consulting services group, acknowledges that something akin to the film noir gumshoe spirit does run in his family.

``Back when my dad started the business, my grandma spent a week tailing a subject in her car, changing her outfit every day to make herself harder to spot,'' he says, smiling at the recollection.

``My family is full of curious people, and that has not changed.'' The patriarch, Jules Kroll, now 64, is a former Manhattan assistant district attorney who came to believe that a lot of the time and money spent prosecuting corporate crime would be better spent trying to prevent it.

With that in mind, he set up the company in 1972.

Though the company was sold last year to insurance giant Marsh & McLennan, Jules Kroll remains its executive chairman.

The younger Kroll, who was in Hong Kong earlier this month to visit clients, graduated in French, Italian and fine arts from Georgetown University in Washington, DC, the same school where his father got his law degree.

A family man, he's the eldest of four children; his sister, Dana Kroll, also works at New York headquarters as an associate managing director.

In nine years with the firm, Jeremy Kroll has risen from investigator in the areas of corporate intelligence and due diligence to head of a division with more than US$500 million (HK$3.9 billion) in annual revenue.

If Kroll Associates enjoys some cloak-and-dagger mystique, it's probably because of the large number of ex-police, military and intelligence officers Jules Kroll originally hired to lend his new company credibility.

Nowadays, its recruits are just as likely to be computer nerds, lawyers, accountants and investment bankers. The company has spread far beyond its beginnings in investigative and security services.

Today, its four primary business segments are consulting, corporate advisory and restructuring, background screening and technology services.

``Technology is a big growth area,'' Jeremy Kroll says. ``Computer forensics is a major weapon in our arsenal.''

The company glories in its reputation as ``Wall Street's private eye,'' a firm that multinationals, and on occasion even the US government, are comfortable entrusting with their most sensitive affairs.

It burnished its reputation in the early 1990s, successfully tracking down millions of dollars of assets concealed by political outlaws like Jean-Claude Duvalier of Haiti, Ferdinand and Imelda Marcos of the Philippines, and Saddam Hussein of Iraq. Less glamorous, but probably more typical of the way Kroll earns its bread and butter, is its mandate, bestowed in 2002, to restructure Enron, the fallen angel of the US energy business.

Kroll booked US$900 million in turnover last year and currently employs more than 4,000 people in 65 offices worldwide.

Kroll fils says the company's security work revolves mainly around emerging markets. ``In some industries, such as oil and energy, there is a need for companies to be in `bad neighborhoods' where it's dangerous to business.''

Does that include China?

Not really, he says. If China were considered that dangerous, he adds, would Yahoo! ever have invested, as it did recently, US$1 billion (HK$7.8 billion) to acquire a 40 percent stake in Alibaba, a narrowly focused Internet outfit in a speculative industry that last year earned just US$46 million?

``Overall, we have seen a maturing view of Greater China over the past five to 10 years, as experience and confidence have increased,'' he says.

Though in earlier years, China may have been just another bandwagon on which globetrotting companies were expected to jump, it has since moved up the charts to become an integral part of many global strategies.

With that, the level of risks has risen proportionately. ``We get daily phone calls from American and European companies about troubles that are threatening their joint ventures in China,'' Kroll says.

The China concerns of Kroll's clients today fall very broadly into three categories - transactional risks, regulatory risks and operational risks. Transactional risks relate to joint ventures and partnerships.

Regulatory risks are those inherent in a company's dealings with Chinese authorities, and operational risks involve issues like technology, supply chains and general ambiguities associated with doing business in the mainland, for example, intellectual property protection.

Kroll also advises on political and societal risks that tend to become more important for companies as their mainland roots deepen.

``Kroll helps clients understand their markets a lot better, and to recognize that China is becoming an influential player in the global marketplace,'' he says.

Financial institutions are also rushing headlong into the mainland but many are plagued by doubts about their clients - as basic, in some cases, as whether they are real or fictitious.

``The real ownership structure of a company and who's behind them are issues that must be dealt with.''

Establishing title is a major headache for real estate investors. Shell companies abound, and it is often unclear just who owns what. I ask Kroll what, after a decade in the company, is his most memorable experience? Surprisingly, it has nothing at all to do with catching someone red-handed in a headline-grabbing scandal. ``No. It's the recovery of a kidnapped child. It happened when I was in my late 20s. The feeling of returning a child safely to his family is beyond description.''

Finally, I can't help asking him if it's true, as some people have suggested, that Kroll people carry guns when they're in China.

``No way,'' he says, laughing. ``The only people in the company who ever carry guns are those involved in personal security protection, but they've never been deployed anywhere in Greater China.''

That's a pretty good indication that Hong Kong and China are not all that dangerous as places to do business.
