The Blackest Mail

Not gonna drag out this one with multiple clews.  Not the worst cover but other than that rather poor cast shadow that rims the foreground figure's right arm there is nothing that indicates (other than the masthead) this to be an adventure of The Shadow.  This is the first of the Bruce Elliott novels and Mr. Olsen says it's bad as a tale of The Dark Eagle but not bad as just a plain mystery novel.  Take it for what you will.
