The Fourth Riddle is interactive fiction based on Turandot.

In the press of the crowd, old Timur's hand was torn from your shoulder. You tried to reach him, but you were too late to grasp his hand again, and you saw him borne away in the surging sea of people, the gulf between you growing ever wider.

Timur is frail and blind. You haven't guided him along such a long, long road to lose him now.
