Looking for some light, entertaining Sherlock Holmes-style stories? You might enjoy this pastiche, written by Derleth prior to the copyright on Sherlock expiring.
Solar Pons, a more avuncular shade of Sherlock, holds court at No. 7B Praed Street. His dull companion Dr. Parker chronicles Pons' cases.
The book contains ten short stories which should entertain. A couple are riff's on Sherlock's adventures. They are not the most intricate of mysteries. If you think about them, the solutions are reachable. But the tales are diverting.
I suspect Derleth wrote "The Adventure of the Orient Express" with his tongue firmly in his cheek after watching one too many espionage-on-a-train movies.
"The Adventure of the Unique Dickensians" is an enjoyable Christmas-time story with an amusing twist at the end.
"The Adventures of the Seven Sisters", with it's sly tip of the hat to Sax Rohmer, actually has some philosophical meat. It poses the question "what types of justice are there, and do some forms of justice better benefit society than others?" It's all the more impressive since the story was written prior to 1973. I refuse to provide a spoiler, so you'll have to read the story to see what I'm talking about.
