Currently I'm listening to The Shadow radio episodes on Audible from the collection entitled "Strange Puzzles." It's a pretty good collection of Shadow mysteries. Here's a summary from the Audible website.
"Music, madness, death, and darkness face amateur criminologist Lamont Cranston and The Shadow. In the midst of the most classic of mystery motifs - from foreboding castles to frame ups - he unravels each remarkable riddle. From elusive treasure to conclusive evidence: How? Why? And, who dunnit?
Let your curiosity lead you through two newly discovered Orson Welles episodes, available here for the first time since their original broadcasts in 1938 - "He Died at Twelve" and "The Black Buddha." Consider the clues in more classic episodes starring Bill Johnstone and Bret Morrison as the cloaked crusader. Ask yourself, is that really Ken Roberts singing in "Tenor With a Broken Voice"?
The Shadow producer and scriptwriter Edith Meiser once said, "A mystery is just a puzzle solved by the detective." Of course, the 18 cases in this digitally restored and remastered collection are cracked by…The Shadow!"

My favorite episodes so far have been "The Black Buddha", "Traffic in Death" and "Mansion of Madness." The stories I haven't cared for too much are "Phantom Fingerprints" and "Murder in E Flat." All in all, so far I'm very pleased with the selection. The audio has been remastered so the sound is clearer and with less static and background noise.
Please note that this collection can also be purchased from Radio Spirits. It comes on 9 CDs and includes a Program Guide by William Nadel with photographs and background information about the series. (This guide is not included if you purchase it from Audible.)
