Once upon a time in 1990s, there was a company that worked in a challenging niche technical area. Unlike competitors who relied on grants and small deals, the company grew, becoming huge, multinational, and public. Except that it was found that the majority of the sales were non-existent. Everything crashed and burned almost overnight, people lost millions, the unfortunates that were acquired ** this bubble, lost their assets.

One of the founders (let's call him L), using deficiencies of the legal system, kept operating other diverse schemes in different parts of the world, on a smaller scale: from food to toys and software. They all kept failing within a year or two when running out of liquidity, but that was fine with L, because he was normally getting someone else to be a majority shareholder and a director - someone he could control.

The last venture was bigger than the rest, and so L had to work with more people. It still looked safe, because they all seemed to be nice, controllable puppets. Except that this time it didn't work out, and some of the directors / shareholders smelled a rat when a large chunk of the money disappeared. While L, via manipulations of the other puppets, was able to get rid of the immediate danger ** removing the troublemakers, the latter ones did not give up; as of today, they have accumulated all the evidence and are pushing for legal options.

The trouble, however, is that L is officially bankrupt. This makes any legal pursuit, especially cross-border, a waste of time and money.

While L has a large clan in two countries that he is feeding, the amounts of money are too large to be spent. Furthermore, as he's been under trial for the 1990s large bubble, he can't spend too much of it without being noticed.

There has been various rumors with some juicy details among the former employees of the 1990s company, that L stashed away a large amount of cash in one of the European tax havens (either Luxembourg, Lichtenstein, Switzerland, or Jersey). They say it's at least in tens of millions. It is known that they've been operating in Asia Pacific as well, specifically, Singapore. The latest activity of L involved mostly Hong Kong for registration and bank accounts.

On the other hand, the companies registry of Hong Kong has an entry for a dissolved company with the same name as the 1990s multinational. This company's owners are other companies, which changed throughout its existence. The owner companies seem to be shell companies registered long before the multinational became multinational. However, they were deregistered a month after the troubles in the multinational started. So it's unclear whether these are connected.

Does anyone have a primer on offshore bank accounts and companies or any advices here where to look for the treasure?
