About the author:

Rolf Österberg (pseudonym) is an ex-commando who served as such for a number of years. His interest in the work of the UN saw him working for them in Africa for a few years. He is currently full-time writer, living outside the Netherlands.


One Woman Crusade was first published in Dutch as De Zaak by Celtica Publishing in 2016. It is the prologue to a series of thrillers that can be read on their own, but have a common dominator in both global terrorism and a number of characters. There are three thrillers yet waiting to be translated from Dutch to English: The Al Qaeda Connection, The Oslo Virus and The Al Qaeda Attack, all previously published in Dutch.


Besides thrillers, Rolf also writes epic fantasy. From December 2014 until December 2018, Celtica Publishing released his The Abyss (De Afgrond), a series of five books.

Rolf Österberg   One Woman Crusade

One Woman Crusade.


A Russian archaeology professor in Jerusalem procures an art portfolio containing a number of papyrus scrolls… and a roll of film. The professor’s disappearance induces his friend, a retired Mossad analyst, to pull out all the stops to find him.


A Dutch student picks up a roll of film on the square by the Wailing Wall and shoves it in her bag, taking it home with her to Holland. Later, upon return from her honeymoon, that little roll of film is responsible for turning her life, and that of the love of her life, into a nightmare.


A tortured, murdered woman is discovered in Amsterdam and the police are desperate to find her killer. All too quickly, the case turns out to be even more complicated than anyone could ever have suspected…


‘One Woman Crusade’ takes you from Israel to The Netherlands, and to Russia and The Balkans. Then there’s The Vatican - prepared to do anything to get their hands on those scrolls, plus the photographs and negatives.


-The plot is interesting and evolves gradually to an instigating situation. The title gets the reader wondering where is the woman who is going to a crusade.  Different places, police and intelligence organizations, and above all a very nasty bunch of evildoers. The Catholic Church and her dogmas are very well confronted. 


The characters are very well elaborated and the author must have done quite some research to outline them so well. The book faces some very current themes and situations skillfully. It has a nice balance of mystery, romance, funny situations, violence and investigation techniques. In short, a very nice reading. I´m looking forward to the sequels.

-Never heard about Österberg as a thriller author, but after reading One Woman Crusade, I hope that more of his thrillers will be translated. Great story, a bit like the Da Vinci Code I got the impression, but easier to read and with many unexpected twists and turns, which makes the end unpredictable. Loved it!

-Good story, exciting with an unpredictable ending to the plot. I think it is getting close to reality where the Catholic Church is trying to defend its dogmas.
