The Saint looked at him. He had a dim suspicion that there was something in Essenden's eyes that should not have been there; but he could not be sure. And yet—what could the trick possibly be? Not more than a device to get rid of the man, in the hope that the woman would be easier to deal with.
Regarded in that way, the idea became ludicrous— to anyone with a scrap of imagination and the slightest knowledge of Jill Trelawney. Yet Simon turned in the doorway and spoke a ridiculous warning.
"Jill," he said, "it's just possible that he's expecting to do something clever when he's got you alone. But the dangerous four are safely trussed up, and Marmaduke's a very silly little man and not at all necessary to the cause of Empire Free Trade—so if he does raise up on his hind legs——"
"You should worry," said the girl. "That's just what I'm waiting for. I've got both eyes on his lordship, and they're not blinking till you come back."
"Good enough, baby," said the Saint, and drifted out.
He went down the hall and found the door under the main staircase without any difficulty. Opening it, he found a switch, and went down a long flight of stone stairs, finding the wine cellar at the bottom, as he had been told he would. By his side, at the foot of the stairs, he found another switch, and with this he was able to light up the cellar. The door at the far end was of massive and ancient wood, heavily barred, and studded with iron. He would have expected such a door to be heavily dusted and cobwebbed; but a faint trace of oil about the hinges was enough to tell his keen eyes that he would not be the first person to penetrate into the passage.
He took down the key. It was bright and newly burnished, and the lock turned easily. Beyond the door, when he had opened it, he found another switch, and this lighted up a row of frosted bulbs along the tunnel that faced him.
A breath of damp, musty air struck his face. He went on cautiously, and with a faint feeling of illogical alertness tingling up his spine—a feeling almost amounting to apprehension. He scowled at the feeling. There was no reason for it—no basis beyond the fact that he had imagined he had caught in Essenden's eye a flicker of an expression whose interpretation had baffled him. But he went on, calling himself every manner of fool, and kept his hand on his gun.
