"Battle of Greed"

 "Rupert Sandersham," came the voice of The Shadow, "you are a man condemned by your own avarice!  You are a master, not of finance, but of greed!"

A boring cover with a not so compelling quote.  This would not have appealed to me if I weren't already a fan.  However this review says try it, you'll like it!

And speaking of the cover, it was the apparent inspiration for this Better Little Book from 1940.
