On the website? Click "Inbox". It's a tab at the top of the page. From there, just click the title of the message you want to read, and it should open the message up for you. The top of the page is the actual message, and the bottom of the page is a list of the message history. (If you replied back and forth a lot, the original messages would show up there for you to reference.)
