Look at this landscape carefully to be sure of recognizing it, if you should travel to Africa someday, in the desert. And if you happen to pass by here, I beg you not to hurry past. Wait a little while, just under the star! Then if a child comes to you, and if he laughs, if he has golden hair, if he doesn't answer your questions, you'll know who he is. If this should happen, be kind! Don't let me go on being so sad: Send word immediately that he's come back
As the Doctor would say, Allons-y!
