The Boy in the Suitcase by Lene Kaaberbol and Agnete Friis
The title is creepier than the book, despite its Nordic crime label. I was expecting something very SVU, but the novel is more interesting than that.
The Boy in the Suitcase is the first in a series featuring Red Cross nurse Nina Borg. Nina is one of those do-gooders who champions the underdog while completely neglecting herself and her family. She is a mild mess, but fiercely committed to doing the right thing even though her execution is frequently flawed.
I look forward to reading the next novel in the series, Invisible Murder.
