Old B&W comedy about unsuccessful murders

[phantompete]

Hi out there,
Trying to remember the name of an old movie that I haven't seen for years. It's an old black and whitey possibly from the 40s or 50s set in rural England. The plot was about someone trying to bump off a rich relative to get an inheritance, but his elaborate traps kept killing the wrong person. Not sure about the ending, but I think the protagonist may have been killed by one of his own schemes. Any suggestions would be greatly appreciated.
Thanks,
Pete.
