Editor's note in The Australian Journal, 4 November 1865, p.156 stated that 'Memoirs of an Australian Police Officer' would alternate in the weekly issues of the journal with the series 'Adventures of an Australian Mounted Trooper' and that 'these naratives will be of the most spirited description, and embrace the most extraordinary adventures and perils that have characterised the history of the colonies'.
Stories in these series were published anonymously but the editor's note states that they are 'from the respective authors of 'The Shepherd's Hut ' and 'The Golden [i.e. Stolen] Specimens'", implying different authors. Some of the stories are attributed by Lucy Sussex to Borlase ( see Introduction to Mary Helena Fortune), and some were reprinted in Borlase's 1867 collection The Night Fossickers. However, there are suggestions that Borlase may have plagiarised Fortune's work or that her work was used to cover a shortfall in Borlase's writing schedule.
