Another Answer, Another Riddle

So Caden figured out that last riddle. The answer was the word "Empty". We also got a new message earlier today. Our stalker delivered it in a suitably dramatic fashion; he nailed it to one of our tires with a knife.

"WHAT SEEST THOU ELSE, LIAR, IN THE DARK BACKWARD AND ABYSM OF TIME?

Zlam abte hm ksull ziizov xhx shesm?"

He wasn't subtle about the codeword though; the word "Death" was carved into the blade of the knife, even someone as utterly oblivious as me could have figured that out. The decoded message was this riddle;

"What type of house weighs the least?"

Again, even a dumbass like me didn't have to think too hard for that one; a lighthouse. Is it just me or have the riddles gotten easier as time goes by? What's the deal with that?

Anyway, the tire situation has delayed us a couple of days, but we'll be back on the road soon. Peace.
