The car went through the tiny village of Chalk Hill, and their talk was suspended.

Further up the road they could see the open; gate which led by a broad field-path to the chalk-pit, the path along which Richard had seen the elephant dragging the other motor-car two evenings ago. Richard directed the car gently through the gate and then stopped; they dismounted, and crossed the great field on foot.

‘If the matter of the silver was all fair and square,’ said Richard, ‘why did your father deal with the coin so mysteriously? How did he excuse himself to you when he asked your assistance?’

‘He didn’t excuse himself,’ said Teresa stiffly.

‘I acted as he told me. I was his daughter. It was not my place to put questions. Besides, I enjoyed the business. Remember, Mr. Redgrave, that I am not a middle-aged woman.’

As they got on to the highest part of the field they saw at the far end the dim shape of the electric car.

They crept cautiously towards it, and saw no sign of Raphael Craig. At length, avoiding the zigzag path that led down into the pit, they reached the point where the chalk had been cut precipitously away. Still moving with all possible discretion, Richard lay on his stomach and looked over. Twenty-five feet below he saw Raphael Craig standing, apparently in an attitude of triumph, over the prone form of Micky, otherwise Nolan, the detective. A lantern held by Craig showed plainly the drawn and stiffened features of the man from Scotland Yard.
