'Murder' is the original name for which board game invented in 1943?

In the US it is now called "Clue", and in Europe and Australia, "Cluedo".

This site says Clue was originally callled Murder, but doesn't look incredibly reliable.

Cluedo was invented by Anthony E. Pratt, a solicitor's clerk from Birmingham in England. He invented the game in 1943 with the help of his wife (who designed the board). In 1948 he submitted it to Waddington's Games in Leeds, who published it for the first time in 1949.

"Cluedo" is a pun on the traditional game "Ludo" (which is also Latin for "I play"); mixed with the word Clue for the murder mystery element. So it's saying Murder Mystery Boardgame in one word. I believe Ludo is not well known in the USA, thus as the pun would not be understood, Parker Brothers probably decided to just call it Clue for marketing reasons.

It was originally named "Murder", but changed its name to Cluedo / Clue before publication.

This is a little better:

Hence, in 1943, Anthony and his wife Elva (1913-1990) began designing a murder mystery board game. The original game was called "Murder!", with the artwork for the board itself designed by Elva
