The Adventure of the Diogenes Damsel (audio story)

 was the forty-third Bernice Summerfield audio story released by Big Finish Productions. It was the third story of the ninth season and featured Straxus, a Time Lord who appeared in several Doctor Who audio adventures. It was also notable for incorporating elements original to the Faction Paradox series, principally the Cwejen, introduced in The Book of the War.

What are the plans of the mysterious Lord Straxus? Who is Ludvig Cooray and what has the number seven to do with all this? Can Bernice acquire the help of Mycroft Holmes, the cleverest man of the age, and more importantly how is she going to get home?
