“Could Ketterä have two wheelchairs?” Koskinen looked at Ulla curiously. “Why were you thinking about that?” Ulla shrugged. “I don’t know. I was just thinking.” “We need to focus more on how Ketterä left Sotkan Street after the taxi dropped him off.” “Mmm,” Ulla said, sipping her hot coffee. “I forgot to mention this morning that I interviewed the physiotherapist. She didn’t know anything about Ketterä’s life—they never really talked. It turns out that during their first couple of sessions, Ketterä tried to grope her, but she made it clear that just one more pat on her rear end would mean he was done with the treatment. After that they never talked about anything but the weather and even then only using two or three words at the outside: ‘it’s raining’ or ‘it’s sunny.’” “Kaatio said that nobody in the surrounding buildings had seen a man in a wheelchair.”
