What is the plot of The Monkeys Paw?

It is a rather disturbing allegory on the ( Three wishes) or ( people always make bad choices) theme which has been used on shows as diverse as Twilight Zone and others of that type. The plot is similar to that about the Chinese Fisherman, the talking fish, and three wishes. It could be argued as a lesson against democracy ( people will make bad choices) and possibly anti-gambling though gambling does not figure in the plot at all. ( unlike Titanic) so it goes. No Like Monkey Paw.
