The Considerate Killer

The "Nina Borg" series finale (after the stunning and twisty Death of a Nightingale) goes out with more of a whimper than a bang, but that is appropriate, since the title character has been laid low by many injuries, both physical and psychological, in previous outings. Danish Red Cross nurse and zealous do-gooder Nina is now divorced from her husband and tentatively entering a relationship with Søren, the detective whom she saved in Nightingale. She's also trying to repair her relationships with her mother, who's been diagnosed with cancer, and her teenage son and daughter, who resent her risk-taking behavior. When she's clubbed in a Viborg parking lot and the attacker asks her forgiveness, Nina must figure out who is after her—and why. Meanwhile, in the Philippines three young man who bonded in medical school become involved in shady dealings.
