Franklin "Frank" Nardi is a character who appears in the expanded Cthulhu Mythos. He was originally created by author C. J. Henderson, but has since been expanded upon by others including Josh Reynolds and Robert M. Price.
Originally of Italian descent, Frank is outwardly a stereotypical hard-boiled New York detective, although he possesses a strong moral compass and is fiercely loyal to his friends. He is somewhere in his late middle age and, although still solidly built for a man of his years, has gained a certain amount of excess weight since leaving the force.
After serving with the New York Police Department - where he attained the rank of detective - Frank chose to take early retirement. Subsequently, he contacted three other former police officers and partnered with them in the Arkham Detective Agency, a private-investigations firm which they established in the supposedly-sleepy town of Arkham, Massachusetts.
Soon after setting up business the group realised that, far from being an ordinary place, Arkham was in fact home to many strange and inexplicable occurrences. In order to exploit this, the Agency branched out from regular detective work into paranormal investigations, a side business which has proven to be extremely lucrative, if at times hazardous.
Behind the Mythos
C.J. Henderson originally created the character of Frank Nardi, whom he used as the protagonist for four short stories before his death in 2014. Before his passing, Henderson pitched the idea of a collection of short stories by contemporary authors based on the character to author and editor Brian M. Sammons, who agreed to the suggestion. This eventually became Arkham Detective Agency; however, due to the speed at which the industry processes such works, the book was not published in Henderson's lifetime.
