Reading Your Inbox for Pleasure?

Is this even possible? It's like reading a book, but instead of turning the pages, you wait for an e-mail to arrive. This "book" is a mystery in written in the form of an e-mail, and every now and then, you get an e-mail -- it appears like an e-mails that the characters are writing each other and they have sent copies to you. Hmmm... I am skeptical, but intrigued!
