I take my girlfriend, Grauben, to her cousin in Leatherhead. Galloping back to return the horse, there is thunder and lightning, and we suddenly see a gigantic machine!

The metal tripod is higher than many houses, and firing a heat ray everywhere! If it sees me I'm dead!
Should I keep going? Or should I turn around? That might take precious seconds! Or should I quickly pull the horse so we fall over, out of sight, into the stream by the road? Or do something else?
