A dark planet in the solar system is an age-old theory, going back to the early modern period, when Neptune, and the larger asteroids, were being discovered.
The hunt for them, and the final laying-to-rest of the planet Vulcan, is the subject of a great book, one of the best history-of-science books I've read.
The Hunt for Vulcan: How Albert Einstein Destroyed a Planet and Deciphered the Universe, by Thomas Levenson.
His other books, including the recent one on Einstein in Berlin, the South Seas Bubble, and Isaac Newton's tenure as Warden and Master of the Royal mint, are all great reads.
