James and Elizabeth, have "retired' to a life of ease in a new time world in 2016 after helping the Martians save the Earth and their own planet.Unfortunately, Elizabeth thought it would be a good idea to visit her ancestral home at Hamgreen to see what had become of it.The problem is, it's difficult to find. Even though it's been there since before the Great Comet and usually there's a Martian sitting on the gate post. However, If you do find it, you will discover time inside the house is often different to that outside. It depends on which door you go through.You really must make sure you are wearing the right clothes when you pay a visit.
