Joe turned up a red, grim face. "He'll talk a lot before I'm through with him," he promised. The sixteen patients from Ward J descended the stairs, were counted through another door, and formed a ragged column of twos on the concrete walk outside. With Joe leading and Wilhart guarding the rear, the little formation moved across the great grassy quadrangle enclosed by the buildings and connecting roofed corridors of the hospital. Potts tried to close his ears to Wilhart's incessant urging of Danny Harris. Harris would do little of his own volition, but Potts was tired of acting as his escort.

A touch of the starter set the 1,000 h.p. radial engine roaring. He waved to the gaping officers and opened the throttle. The bi-plane whisked down the field and rocketed into the blue morning sky. Too late, Potts saw the buzzard soaring dead ahead. He
