Today's edition of Friday's Forgotten Books lead off with the out of print BDB title, East of Singapore, and ends with the current BDB title Empire of the Devil, both by Frederick Nebel.
Our astute reviewer writes:
"East of Singapore provided a rare opportunity to see Black Mask writer Frederick Nebel applying his talents to exotic adventure in the Far East. That Nebel wrote such tales was only natural, because when this one first appeared, as "Somewhere East of Singapore," in the July 1926 issue of Action Stories, the market for adventure stories was much larger than that for mysteries."
