"Ya sit Ayisha,"* said Grim, "I carry a letter to Sheikh Ali Higg from some one in Arabia. I will deliver you along with the letter. You may have a place in my caravan—provided you have camels, provisions, and a litter," he added; for the surest way to increase her already alert suspicion would have been to offer to provide everything. [* O lady Ayisha.]

"Let me see the letter!"

Grim produced one instantly—an envelop with a big red seal on it. It was marked across the top in large letters "On His Majesty's Service," but addressed in Arabic to somebody, and as she could not read she was satisfied.

"Ali Higg will hold you answerable for my safety if he has to destroy armies to reach you!" she said simply.

"Ya sit Ayisha," Grim answered solemnly, "may Allah turn my face cold if Sheikh Ali Higg shall have fault to find with me in this matter!"

"How many is in your caravan?" she asked. "Twenty armed men."

She nodded. "I will pay for my place in the caravan, according to the custom—the half now and the other half on arrival."

Without gesture, without moving a muscle of his face, Grim turned down that proposal desert-fashion, that is emphatically, with a reservation.

"Ya sit Ayisha, may Allah do so to me, and more, if I will accept a price for this. Between Ali Higg and me let this thing be."

"Taib," she answered. "My men shall look for camels. I will go with you tonight."
