Editing August Derleth (section)

===Detective fiction and "Solar Pons"===
Detective fiction represented another substantial body of Derleth's work. Most notable among this work was a series of 70 stories in affectionate pastiche of [[Sherlock Holmes]], whose creator, Sir [[Arthur Conan Doyle]], he admired greatly. The stories feature a Holmes-styled British detective named [[Solar Pons]], of 7B [[Praed Street]] in London. These included one published novel as well (''Mr. Fairlie's Final Journey''). The series was greatly admired by such notable writers and critics of mystery and detective fiction as [[Ellery Queen]] ([[Frederic Dannay]]), [[Anthony Boucher]], [[Vincent Starrett]], and [[Howard Haycraft]].

In his 1944 volume ''[[The Misadventures of Sherlock Holmes]]'', Ellery Queen wrote of Derleth's "The Norcross Riddle", an early Pons story: "How many budding authors, not even old enough to vote, could have captured the spirit and atmosphere with as much fidelity?" Queen adds, "his choice of the euphonic Solar Pons is an appealing addition to the fascinating lore of Sherlockian nomenclature." Vincent Starrett, in his foreword to the 1964 edition of ''The Casebook of Solar Pons'', wrote that the series is "as sparkling a galaxy of Sherlockian pastiches as we have had since the canonical entertainments came to an end."

Despite close similarities to Doyle's creation, Pons lived in the post-World War I era, in the decades of the 1920s and 1930s. Though Derleth never wrote a Pons novel to equal ''The Hound of the Baskervilles'', editor Peter Ruber wrote that "Derleth produced more than a few Solar Pons stories almost as good as Sir Arthur's, and many that had better plot construction."

Although these stories were a form of diversion for Derleth, Ruber, who edited ''[[The Original Text Solar Pons Omnibus Edition]]'' (2000), argued: "Because the stories were generally of such high quality, they ought to be assessed on their own merits as a unique contribution in the annals of mystery fiction, rather than suffering comparison as one of the endless imitators of Sherlock Holmes."

Some of the stories were self-published, through a new imprint called "[[Mycroft & Moran]]", an appellation of humorous significance to Holmesian scholars. For approximately a decade, an active supporting group was the Praed Street Irregulars, patterned after the [[The Baker Street Irregulars|Baker Street Irregulars]].

In 1946, Conan Doyle's two sons made some attempts to force Derleth to cease publishing the Solar Pons series, but the efforts were unsuccessful, and were eventually withdrawn.<ref>Peter Ruber.

Derleth's mystery and detective fiction also included a series of works set in Sac Prairie and featuring Judge Peck as the central character.
