1Q84 Book 3: October - December by Haruki Murakami

Ushikawa found it hard to get his head around the idea that the elderly dowager who lived in a mansion in Azabu could somehow be involved with the assassination of Sakigake's Leader. He had dug up background information on her. She was a well-known figure in society, so the investigation had not taken much effort. Her husband had been a prominent businessman in the postwar era, influential in the political sphere. His business focused mainly on investments and real estate, though he had also branched out into large-scale retail stores and transport-related businesses. After her husband's death in the mid-1950s, the woman had taken over his company. She had a talent for managing business, as well as an ability to sense impending danger. In the late 1960s she felt that the company had overextended itself, so she deliberately sold-at a high price-its stock in various fields, and systematically downsized the business. She put all her physical and mental strength into the remaining areas.

Thanks to this, she was able to weather the era of the oil shock that occurred soon after with minimal damage and set aside a healthy amount of liquid assets. She knew how to turn other people's crises into golden opportunities for herself.
