Scandinavian crime fiction

Sadly I'm reading the last of Arnaldur Indriðason's books featuring Erneldur the detective. I've decided to move on to a couple of other Scandinavian authors, including someone who's apparently quite well known and popular, Henning Mankell. I'm also going to get two books by another Icelandic author, Yrsa Sigurðardóttir. I'm curious if anyone on my flist has read either Mankell or Sigurðardóttir and, if so, what comments you have about them. Thanks for any input that you have!
