Levelling the pistol she pressed the trigger. The Arab captain threw up his arms and staggered upon the almost exhausted Peter, bearing him to the deck together with the fellow whom he had used as a human shield.

Still at a loss as to the outcome of the fight, Olive waited, finger on trigger, watching the writhing forms almost at her feet. Presently the Arab sailor extricated himself and fumbled for the knife in his sash.

Again the pistol cracked, and the fellow collapsed in a limp heap across the body of the captain of the dhow.

Checking her almost irresistible inclination to ascertain whether Peter was dead or alive, the girl made her way aft, remembering that there were five Arabs and that only four had been accounted for.

A loud, very masculine-like voice, uttering a string of curses that would have done credit to a Thames bargee, greeted Olive's ears. As she stooped to clear the low poop she was just in time to see Mrs. Shallop deliver a clean and beautifully timed punch on the point of the Arab's jaw. The luckless fellow, lifted completely off his feet, crashed heavily against the bulkhead and slithered limply upon the deck.

This much Olive saw by the aid of a horn lantern hanging from the deck-beam. Then, as Mrs. Shallop turned, the girl was also aware that there was a knife sticking into the woman's left shoulder.

Olive offered her assistance. Mrs. Shallop, seemingly aware of the knife for the first time, waved her back.

"Nothing to make a song about," she protested in a gruff voice. "When I want your help I'll ask for it—not before."

And with this ungracious refusal Mrs. Shallop went back into her cabin and shut the door; leaving Olive, feeling considerably bewildered now that the reaction was setting in, standing close to the unconscious Arab.

It was some moments before she pulled herself together sufficiently to go on deck. By this time the dhow had run up into the wind and was gathering sternway with her lateen foresail aback. Olive hardly heeded the fact. Her first care was to ascertain whether any of the three were still living.
