I rather enjoyed the 1954 A Kiss Before Dying, by Gerd Oswald, except that much of the acting needs to be more grounded and the plot is mediocre. Re the former, for example, Robert Wagner seems to care little about his part. Re the latter, for example, apparently no one saw Wagner (as Bud) and Joanne Woodward (as Dorothy) together as they ambled up to the roof of a tall building where Bud murders Dorothy. Everybody but everybody thinks she committed suicide.
There is sapid suspense, though.
