Communication in 1950s

I think the lack of communication technology in the 1950s helps Tom’s murder plot. Without cell phones and internet, it would be more difficult to get in contact with someone in another city. Since Marge and the dead Dickie communicate through letters (via Tom), Tom is able to pull off Dickie’s impersonation by mimicking his handwriting and way of expression through words. Since no one is aware of where “Dickie” is staying, there is no way to contact him through a land line. This means letters are the only way of communicating.
If this act Tom is pursuing would have been less likely if it had taken place in 2010. With the technology like Facebook and Twitter, it makes it very easy to get in contact with others. Tom’s would have been busted 30 pages ago.
