oward Assiout," she thrust
in. "We'd have walked right into some trap of his!"

"Lord knows what we ought to have done! Lord knows what we ought to
do now!"

"Just keep on going," she encouraged. "We can't be very far from
Girgeh, can we?"

"I don't know," said Billy soberly. "It may be half a day or a whole
day more--you remember how vague that old woman was last night...!"
Bitterly he added, "And I'm afraid you've got a chump of a guide."

just saw him on top of a little hill. I suppose they can see us?"

"Probably." Billy's face was grave. If they continued their winding
path in from the desert to the intervening hills that shut them from
the Nile valley, and the horsemen continued their course along the
base of those hills, they would soon meet.

"Do you mind speeding up
