The cover of Darling, I Hate You by T.S. Matthews tells you it was originally titled To the Gallows I Must Go. We consider that too much information, but yeah, this book is about a man whose latest sexual partner wants him to kill her husband. Matthews didn’t write many novels, but he built a significant career as an editor, working at The New Republic and Time before jettisoning the U.S. to live in England, where he wrote books and moonlighted as a reviewer for New York Times. However, the above debuted in 1931. He wouldn’t publish a second book for more than twenty-five years. This Popular Library edition from 1953 has pretty nice art, but sadly it’s uncredited.
1947—Heyerdahl Embarks on Kon-Tiki
Norwegian ethnographer and adventurer Thor Heyerdahl and his five man crew set out from Peru on a giant balsa wood raft called the Kon-Tiki in order to prove that Peruvian natives could have settled Polynesia. After a 101 day, 4,300 mile (8,000 km) journey, Kon-Tiki smashes into the reef at Raroia in the Tuamotu Islands on August 7, 1947, thus demonstrating that it is possible for a primitive craft to survive a Pacific crossing.
