In my view all 4x entries can be combined. Goodreads is then just missing a 2nd edition which was published in 1980 by Pitman in Carlton, Victoria (Australia): https://trove.nla.gov.au/work/7487234...
I've also taken photos of the copy I own (which is the 3rd [1983] edition): https://imgur.com/a/rwUzTHR -- this provides a better photo than the one that's currently attached to the Goodreads listing! - R
Combined the editions you mentioned, also a couple of others I found. Added the 1980 edition. The link you provided for the 1983 edition cover was broken, I used cover image from AbeBooks.
Could you please edit the topic title to start with "DONE".
1. https://www.goodreads.com/book/show/1... - this is the 1st (1947) edition, which was a novelisation of a film by the same name released in the same year
2. https://www.goodreads.com/book/show/1... - a 1963 reprint with a changed subtitle
3. https://www.goodreads.com/book/show/1... - a 1968 reprint (which I suspect, but do not know for certain, has the same cover as the 1963 reprint)
4. https://www.goodreads.com/book/show/8... - a 1983 (3rd) edition, released to coincide with the remake of the film
