"Give it the gas!" the passengers yelled. "Give it hell!"

The driver reacted automatically and pressed his foot down on the gas with everything he had. The bus shot ahead, wildly out of control, and headed into a zig-zag course toward the house. In the path there suddenly loomed a pair of distracted figures who, at the sound of the churning bus, looked back and instantly froze in their tracks.

"Julie!" Marc screamed, leaping from his seat and fighting his way to a position beside the driver. "Julie! Run!"

Outside, Julie merely covered her face with her hands. "Oh, Lord!" she wailed. "Now he's after us with a bus!"

At the last second Marc grabbed the wheel from the driver and yanked at it furiously. The bus careened to one side as Julie and Mario leaped or fainted to the grass, out of the way. The bus roared on, while in the background the siren hurled its piercing tone to the sky. Somewhere in the distance a voice barked hoarsely.

"Fire!" it bellowed. "Get 'em in the tires! That bus is packed with lunatics!"

There was an instantaneous volley of gunfire and suddenly the bus skittered to one side, teetered precariously on two wheels, then righted itself and plunged dead-on into the substantial trunk of a weeping willow. There was a thunderous crash, a rising chorus of terrified voices and then silence.

By fighting her way through the mass of struggling bodies in the aisle, Toffee managed to reach Marc's prone figure. She dropped down beside him and drew his head gently into her lap.

"Are you all right?" she asked.

Marc opened his eyes and looked at her mistily. "I think so," he said. "I feel so drowsy, though." Then suddenly he frowned.
