The sound of a motor-car horn was borne faintly in upon them. In a few minutes the housekeeper ushered Green and Malley into the room. The chief inspector returned Foyle's greetings and flung his heavy overcoat on to a chair. His eyes wandered over the prisoner

with a little pardonable curiosity. Grell bore the inspection with a smile.

"I congratulate you, sir," said Green. "We'll have the thing fairly straightened out in a day or two now."

"I hope so," said Foyle. "Mr. Malley, will you stay with this gentleman for five minutes? I want to speak to you in another room, Green."

He led the way to the little sitting-room, through the window of which he had effected an entrance. A look of comprehension spread over Green's face as he noticed the missing diamond pane. "Malley told me he passed you in the village yesterday. You got our man quicker than I should have thought possible in the circumstances. How did he take it?"

The superintendent gave a brief recapitulation of the steps he had taken since he left London. Green rubbed his grizzled head and followed the recital with keen appreciation. It did not occur to him to feel hurt that Foyle had acted independently.

"As a matter of fact," he said, "I've got a search-warrant in my pocket, and we were coming over this house to-day. I didn't anticipate much profit, because he could have easily slipped away into the woods. I got the county constabulary to put a cordon of patrols round about, and hoped to drive him into their hands. But it was a slim chance. However, we've got him now."

"Yes, we've got him now," agreed Foyle. "There only remains the Petrovska woman, and we'll have her to-day. Listen."

He told of what he had learned from the housekeeper, and they discussed the probabilities of the woman reach

ing Dalehurst Grange. If she managed to escape Blake and the other detectives who were hot-foot on her trail there was little doubt but that she would walk blindly into a trap. That she had not already reached the Grange and departed Foyle was satisfied, although she had had ample time to travel from Liverpool. As Green phrased it, "she might almost have walked it." But the exigencies of the pursuit might have brought about delay if she attempted to confuse her track. If Foyle had been able to get in touch with Blake he would have called him off in order to let her proceed unfettered. That could not be done.
