The major nodded.

"Funny," the captain said. "I never met Darville, you know. But last fortnight I bumped into his wife. Ploving her name was. Plucky. Air warden in the Dover area. Caught hell there. Lost an arm eight months ago, but do you know, she wouldn't quit. Not her. Back on duty and one of the best they've got."

Steve Darville stumbled blindly to the door and up the steps. Out on the path he did not turn to look back at the shell of the manor, black and gaunt and desolate against the sky.

His hands shook as he reset the dial readings and pulled the control. He saw the needles sway and dance. He was hardly aware of it when they ceased swaying. Numbly he reached for the door latch.

Inside the workshop was the bright glow of bulbs. A stiff breeze blew in at the open window. Instinctively, Darville glanced at his wrist watch. He had been away, in that future that was not his future, for less than three-quarters of an hour.

Professor Ploving's eyes met his, read the frustration there. The older man said nothing, but put a hand out to the smooth surface of the tube and buried his face in his arm.

Darville slipped quietly out of the workshop and up the familiar path, moonlight-flooded between the orchard trees. At the orchard's edge he halted; stood listening to the gay abandon of the music and the voices, searching that blob of light and color for Jean. She was standing at the edge of the lawn, a little apart from the others.

Stephen Darville went to her quickly, smothered her cry of pleased surprise with a quick kiss and led her to the jerry-built dance floor. Together they caught the tom-tom rhythm, moved into the circling stream of the dancers.

"Steve," she said, her voice eager, "do you have to go back tonight?"

"Not tonight or ever," he said.
