A chill went down Rick's spine. Instead of a solution, they had found a deeper mystery. He was sure of only one thing for the present. They should not wait at the house of Fuad Moustafa.

"Come on," he said. "Back to the hotel. If we can't have facts to feed on, we can at least have that sandwich."

The boys ordered, then got undressed. Scotty went in to wash up while Rick wrote cards to the folks at home. A knock interrupted him. "Must be the porter," he called to Scotty, and went to open the door.

A stranger stood there, a big man in an immaculate gray linen suit. He wore thick eyeglasses with stainless-steel rims. On his curly hair was a tarboosh of red velvet. In his hand was a gleaming, snub-nosed hammerless revolver, pointed at Rick's midriff.
