The series title is from the title of the second novel in the series "The Liebermann Papers" by Frank Tallis.
The series aired in the UK with a 3x90' run time while the US opted for the 6x45' cut of the show.
Creator Stephen Thompson was a writer on "Sherlock" and "Doctor Who". There are some similarities in terms of the relationship between Lieberman and Rheinhardt & between Sherlock and Watson in that series.
In France this series is called 'The Journals of Max Lieberman'
