The Case of the One Eyed Witness

I have come back to the mystery book I was working on called Perry Mason and the Case of the One Eyed Witness. So far, I am not completely liking the book. I feel like the case that the detective/attorney is working on is already to convoluted, and some aspects are not to clear. Yet, some of these parts of the story reference to the time period it was originally written in, the 1950s, which means that it is written using a style and mentioning items and ways of life that I am not familiar with.
