Blomkvist is such a wuss. He can't remember if he's ever felt so cold before, and it's only -15 C out. He's not dressed for it, apparently, but still. What dolt walks around in a light leather jacket when it's -15 out?
The temperatures are stated in Fahrenheit, which is annoying. Is this due to the translator or did Larsson actually write the temperatures in Fahrenheit?
I know a lot of people (ok, Americans) are more comfortable with Fahrenheit, but I had to look up what 0 F and 5 F were (-18 C & -15 C respectively).
