He made his way downstairs in silence, musing as he went. At the foot of the staircase he encountered Deborah.

"Which are the passages in this lower part of the house that lead to the East Wing?" he inquired.

"Not any of them, sir," answered Deborah promptly. "At least, not any that are ever opened. At the end of the stone passage there's a heavy door, barred and bolted, that leads to other passages, I believe, and to other heavy bolted doors, and they lead into the East Wing. That's what I have heard say. The only entrance in use is the one through Mr. Drewitt's rooms."

Opposition seemed only to strengthen the will of Mr. Inspector Poole. "Into the rooms I mean to make my way," he said to Mr. Ravensworth, as he retraced his steps up the staircase. "Could you not," he hastily added, "get Lady Level to bring her authority to bear upon old Drewitt?"

It was the appearance of Lady Level that probably induced the thought. She, looking pale, haggard and uneasy, was peeping down at them, and did not escape in time.

Arnold Ravensworth somewhat hesitatingly acceded. They wished to speak to Mr. Drewitt—he put it to her in that way—but he had bolted himself into his rooms; would she use her authority and bid him admit them?

She complied at once, unsuspiciously. Of all parts of the house, that occupied by the steward must be most free from concealment. And she went with them to the barred-up door.

The steward did not presume to dispute Lady Level's mandate, which she gave somewhat imperiously. She entered with them. They found themselves in the old gentleman's sitting-room, and he placed chairs for them. "We have not come to sit down," said Mr. Poole; and he passed into the other rooms in rapid succession: the two bed-chambers and the unoccupied room that had nothing in it but a few trunks. A very cursory inspection convinced him that no person was being harboured there.

"Why could you not have admitted us just now, Mr. Drewitt?" he asked.

"Because you brought not the authority of either my lord or my lady," answered the faithful old retainer.
