Poor script?
Getting in trouble because you got rid of the corpse of the man that is evidently not killed, but died of some disease he had? and than not throw out from your car the only witness in the world who knows what you did, before she finds out your name or who you are? either the version i watched was somehow cut (i got the impression of very strange editing) so i missed some explanations, either the script is really bad...
Also, Ann Savage's performance (Vera) was forced and unnatural.
I do love noirs, but this one is fail.
