Central Vienna, Austria. The headquarters of Rosenberg Partners stood among stone buildings that still bore the marks of the Habsburg era.

He had come straight from the airport to headquarters to get through the reports that had piled up.

The first page held Ha Tae-ung's photo and a short profile.

"Confirmed assets?"

"They're hard to pin down. His visible investment returns in Korea alone come to 6.7 billion euros. But the money he actually has working is likely bigger than that."

"What makes you think so?"

Six point seven billion euros. The figure alone had already put Alexander on edge. That wasn't the kind of money an individual investor could make.

And there was separate money working overseas, on top…
