Winterlude, book 2.5 (60 page book)
blurb:

Spoiler:

It's a bitter winter morning when Sergeant Gunnhildur is called to the scene of a violent killing in an abandoned industrial unit. Gunna and her sidekick Helgi quickly find that the battered victim had no shortage of enemies.

The case takes Gunna around Reykjavík's darker side and Helgi to the bleak rural district he grew up in as they work out who was prepared to take a grudge as far as murder.

Summerchill, book 4.5 (142 pages)
blurb:

Spoiler:

It's the tail end of a hot summer when half of Reykjavík is on holiday and the other half wishes it was. Things are quiet when a man is reported missing from his home in the suburbs.

As Gunna and Helgi investigate, it becomes clear that the missing man had secrets of his own that lead to a sinister set of friends, and to someone with little to lose who is a fugitive from both justice and the underworld.

It becomes a challenge for Gunna to tail both the victim and his would-be executioner, racing to catch up with at least one of them before they finally meet.
