Interesting Charles Copeland cover art for Victor Canning’s 1955 adventure thriller Twist of the Knife, published outside the U.S. as His Bones Are Coral. It’s the story of a drug smuggler flying contraband from Sudan to Egypt who crash lands near the town of Suabar, gets involved in a caper to raise gold from the waters of the Red Sea, and of course beds the only white girl within sight. This was actually made into a really bad Burt Reynolds movie called Shark! in 1970.
