New Book: ‘A Deeper Betrayal’

Today marks the publication day of A Deeper Betrayal, the third installment of Kaja Nygaard’s acclaimed Martha Krogh series.

Risavika, Stavanger. One of Norway’s most industrialized areas, filled with companies with major financial interests and people who dislike having the police show up at their door. Here, in the waters lapping at the shore, a man is found dead. Police officer Martha Krogh is stumped: the man is sharply dressed, seemingly without injuries, and carrying an employee card issued by the local university – a card that belongs to a woman called Elena Kurbats. Martha’s gut feeling blares. What was the man doing down by the water with someone else’s ID in his pocket? And how is Elena Kurbats connected to the man the tide is slowly claiming? As the questions multiply, and the answers remain elusive, Martha must take a gamble on who she can trust – knowing that the consequences of the wrong choice could prove detrimental.

In this suspenseful novel, our beloved protagonist Martha Krogh must navigate both a complex murder investigation and the shadows of her own past. Tense and compelling, A Deeper Betrayal reveals the true cost of loyalty, and the harrowing truth that those meant to protect us may sometimes be the ones we most need protection from.

A Deeper Betrayal is published by Bonnier Norsk today, March 13th, 2026.
