The premise is that Solar Pons is the reincarnation of Sherlock Holmes.

In 1928, at the age of nineteen, college student August Derleth wrote to Sir Arthur Conan Doyle asking him whether he planned to produce more Sherlock Holmes stories, and if not, then he, Derleth, would begin a series of pastiches of his own. Sir Arthur promised nothing, so Derleth went ahead, creating Solar Pons. Between Pons' first appearance in 1929 until Derleth's death in 1971, the bite of the Sherlockian bug prompted him to write more than seventy Solar Pons adventures in the best Holmes tradition. Now, restored from the original 1965 Mycroft and Moran edition, Solar Pons is back in this fifth collection, The Casebook of Solar Pons, containing twelve incredible adventures, including the eerie matter of "The Whispering Knights", the surprising affair of "The Haunted Library", and the mysterious adventure of "The Sussex Archers". This newly restored edition also includes the sixth Pons collection The Novels of Solar Pons, featuring the only two Pons novels that Derleth ever penned - the Golden Age style Mr. Fairlie's Final Journey (1968) and the Sax Rohmer-influenced Terror Over London, written when Derleth was a young man in his twenties, and then filed in his papers and lost, only to be discovered decades after his death. Each of these tales are guaranteed to delight both Pensions and Sherlockians!

The steadily expanding devotees of the Sherlock Holmes of Praed Street will hail with delight this crowning volume in a series of collections which have now pastiched the entire quintet of the Master's adventures. Here is another collection of "as sparkling a galaxy of Sherlockian pastiches as we have had since the canonical entertainments came to an end," as Vincent Starrett - who contributes a preface to this book - wrote in his introduction to the first collection of the adventures of Solar Pons twenty years ago.A dozen new Pontine exploits round out the quintet in these pages - from The Adventure of the Sussex Archers to The Adventure of the Innkeeper's Clerk - and between these two tales are such memorable stories as The Adventure of the Haunted Library, The Adventure of the Intarsia Box, The Adventure of the China Cottage, The Adventure of the Crouching Dog, The Adventure of the Whispering Knights, and others, including among them The Adventure of the Missing Huntsman - in which Pons and Parker invade the fox-hunting country of England, and The Adventure of the Ascot Scandal, one of Pons' briefest and most amusing problems.To supplement the tales, the distinguished British author, Michael Harrison, contributes a monograph exploring the background of Dr. Lyndon Parker, and, in the course of so doing, explains the doctor's semi-American English. And, finally, August Derleth has added an Afterword in which he sets forth the facts about the origins of Solar Pons, admitting that it was never his "intention to do any considerable number of pastiches" and relating the circumstances surrounding the continuing numbers of the tales, ending happily with, "I cannot promise to write no more of them."The present collection brings the total number of the Pontine pastiches to 57 - one more than the total of the canonical short stories, of which a reviewer for The Louisville Journal-Courier wrote, "These tales recall, as nothing else has done, those delicious days and nights in Baker Street, days and nights that have vanished forever."- From the original 1965 Mycroft & Moran edition dust jacket

August Derleth created in Solar Pons a detective whose genius cannot be matched, perhaps not even by Sherlock Holmes himself. Now the pen has passed into the hand of the noted British author Basil Copper. Here are six superbly crafted tales of suspense in the best tradition of Solar Pens. Come to Number 7B Praed Street, where the master awaits.

Thirteen short stories depicting the further adventures of Solar Pons, whose prototype is Sherlock Holmes. Includes three stories published in a limited edition in 1952 as "Three problems for Solar Pons".
