I like hard SF and I like crime fiction. Simon Petrie, a physicist, knows his science and is an enthusiastic reader and writer of crime fiction - in his case, SF crime fiction. Usually it's humorous, but this one is utterly serious.
Guerline Scarfe is a forensic psychologist living on Titan, where there is a colony. Her latest case: a girl who has gone out into Titan's freezing, lethal atmosphere and pulled off the helmet of her spacesuit. Why would a well-balanced girl with no particular reason for committing suicide do so? And why in that particular manner? As Guerline says, it's a nasty way to die.
Guerline Scarfe is determined to find out, no matter how many people are trying to stop her, some in lethal ways. That, of course, is a standard trope in crime fiction, but no less enjoyable for it. And it is a very good piece of writing and I will be reading the next one if I get the chance.
My only two gripes with this are as follows: firstly, the title. I have a copy and kept forgetting it. Something shorter and simpler next time! Please! Secondly, there were some scenes which told us about the heroine's background, but didn't really move the story forward. However, I'm going to assume that these will play a more important role in the next book.
Still, a well-written piece of crime fiction in a believable world. I finished it in about two sittings and I only took that long because I had other commitments.
