Free Spiral by Kôji Suzuki Page B

wanted to see a man turn embarrassment into energy and engage in a genuine struggle toward maturity. If the man did that, she'd resume the friendship any time. But she could never be friends with a guy whose psyche remained forever, and unabashedly, that of a child who refused to grow up.
    Ryuji was the only man she'd ever been serious about. He wasn't like the juveniles who surrounded her. The things she and Ryuji had given each other were invaluable. If she could be sure that a relationship with Ando would be like the one she'd had with Ryuji, she'd accept any number of dinner invitations from him. But she knew from experience that the chances weren't very good. The likelihood, in Japan, of her meeting an independent guy, a man worthy of the name, was close to zero. Still, she couldn't quite put Ando out of her mind.
    Just once, Ryuji had mentioned him to her. The conversation had been about genetic engineering, when suddenly he'd digressed and dropped Ando's name.
    Mai hadn't ever understood the difference between genes and DNA. Weren 't they just the same thing? Ryuji had set about explaining to her that DNA was the chemical material on which hereditary information was recorded, while a gene was one unit of that nearly infinite amount of hereditary information. In the course of the discussion, he'd mentioned that the technology existed to break DNA down into small segments using restriction enzymes, and to rearrange it. Mai had commented that the process sounded "like a puzzle". Ryuji had agreed: "Absolutely, it's like solving a puzzle, or deciphering a code." From there, the talk had digressed, until Ryuji was telling her a story from his college days.
    When Ryuji had learned that the nitty-gritty of DNA technology involved code-breaking, he'd started to play cipher games with his friends in med school, between classes. He told her an interesting anecdote about these games. Many of the students were fascinated by molecular biology, and so, before long, Ryuji had recruited about ten guys to play with. The rules were simple. One person would submit a coded message, and then everybody else would have a certain number of days in which to decipher it. The first one to get it right won. The game tested their math and logic skills, but also required flashes of inspiration. The guys loved it.
    The codes varied in difficulty, depending on the skill of the person devising them, but Ryuji had been able to solve most of them. Meanwhile, only one classmate had ever been able to crack any of Ryuji's codes. Mitsuo Ando. Ryuji told Mai how shocked he'd been when Ando had broken his code.
    I got chills. It was like he'd read my mind.
    And so the name Mitsuo Ando had made a deep impression on Mai.
    Which was why she'd been so astonished when the detective had introduced her to Ando at the M.E.'s office. He had to be the Ando-he'd even introduced himself as an old friend of Ryuji's. Knowing Ando had been the only one to ever unlock one of Ryuji's codes, Mai had felt she could trust him. She just knew his skills with the scalpel had to be way up there, and that he'd easily figure out the cause of death.
    Mai was still under the sway of the words of a man who'd been dead for two weeks. If Ryuji hadn't mentioned Ando to her, she probably never would have been able to call the M.E.'s office to ask about the cause of death; she never would have ended up seeing Ando again on campus. She certainly never would have made plans to have dinner with him. One chance word from Ryuji had subtly bound her.
    Mai turned off the main road into a maze of residential streets. There she spotted a convenience store sign that she recognized. She knew where to go from there. Once she turned at the convenience store, Ryuji's parents' house would be straight ahead. As two-week-old memories started to come back to her, she quickened her step.
    It was a nondescript house, built on a parcel of about four hundred square yards. From the wake, she remembered that the first
