I can also recommend the book “Assault in Norway”, which is based on interviews with many of the participants, and includes the equally remarkable stories of their escape from Norway afterwards.

In addition, NRK (the Norwegian Broadcasting Corporation) produced an excellent 6 part dramatisation earlier this year, titled “The Heavy Water War” (retitled as “The Saboteurs” in the U.K.), which is available on (Region 2) DVD/Blu-Ray.
