Allen came from the bar, having quenched his thirst for the time being, and they started off, arriving back at Bittermeads fairly early in the evening, for Dunn had brought them along at a good rate, and apparently remembered the road so well from the afternoon that he never once had occasion to refer to the map.

He took the car round to the garage, and Allen and Ella went into the house, where Allen made his way at once to the breakfast-room, searching for more whisky and cigars, while Ella, after a quick word with her mother to assure her of their safe return, went to find Deede Dawson.

“Ah, dear child, you are back then,” he greeted her. “Well, how have you enjoyed yourself? Had a pleasant time?”

“It was not for pleasure we went there, I think,” she said listlessly.

He looked up quickly, and though his perpetual smile still played as usual about his lips, his eyes were hard and daunting as they fixed themselves on hers. Before that sinister stare her own eyes sank, and sought the little travelling set of chessmen and board that were before him.

“See,” he said, “I've just brought off a mate. Neat isn't it? Checkmate.”

She looked up at him, and her eyes were steadier now.

“I've only one thing to say to you,” she said. “I came here to say it. If anything happens at Wreste Abbey I shall go straight to the police.”

“Indeed,” he said, “indeed.” He fingered the chessmen as though all his attention were engaged by them. “May I ask why?” he murmured. “For what purpose?”

“To tell them,” she answered quietly, “what I—know.”
