everywhere these days. This plane acted strangely. It seemed at first to be coming straight toward her. Then it took a broad sweep and began to disappear. “Like some old marauding crow going back to tell his friends,” she thought. “Hope Sparky won’t be long. But then, of course, in that cramped place he can’t work fast. Just have to be patient, that’s all.” The truth is that Sparky had not even started repairing the engine. There were, he had discovered, other matters that needed attending to first. All the time Mary was watching the sky. The plane out there on the edge of the horizon had reappeared.

Hissing like a snake, the little man snatched a knife from his belt. One moment it hung in air, the next it rattled against the wing’s floor. A heavy wrench had crushed against the Jap’s arm,
