You soon arrive at a double door in the left-hand wall.  You listen at the door but hear nothing.  You try the handle, it turns and you open the left door slightly and peer through the crack.  An armed warrior is lying face down on the floor of a bare room with smooth walls and a low ceiling.  He is presumably dead, for he makes no movement even when you call out to him.  A large jewel, perhaps a diamond, lies just beyond his outstretched arm.<br/><br/><em>Your choices are to enter the room and take the jewel, or to continue north.</em>
