But at last Lizzie went, and, closing the door behind her, Miss Cornelia proceeded more or less to think, out loud.
"Suppose," she said, "that the Bat, or whoever it was shut in there with you, killed Richard Fleming. Say that he is the one Lizzie saw coming in by the terrace door. Then he knew where the money was for he went directly up the stairs. But that is two hours ago or more. Why didn"t he get the money, if it was here, and get away?"
"He may have had trouble with the combination."
"Perhaps. Anyhow, he was on the small staircase when d.i.c.k Fleming started up, and of course he shot him. That"s clear enough. Then he finally got the safe open, after locking us in below, and my coming up interrupted him. How on earth did he get out on the roof?"
Bailey glanced out the window.
"It would be possible from here. Possible, but not easy."
"But, if he could do that," she persisted, "he could have got away, too. There are trellises and porches. Instead of that he came back here to this room." She stared at the window. "Could a man have done that with one hand?"
"Never in the world."
Saying nothing, but deeply thoughtful, Miss Cornelia made a fresh progress around the room.
"I know very little about bank-currency," she said finally. "Could such a sum as was looted from the Union Bank be carried away in a man"s pocket?"
Bailey considered the question.
"Even in bills of large denomination it would make a pretty sizeable bundle," he said.
But that Miss Cornelia"s deductions were correct, whatever they were, was in question when Lizzie returned with the elderberry wine.
Apparently Miss Cornelia was to be like the man who repaired the clock: she still had certain things left over.
For Lizzie announced that the Unknown was ranging the second floor hall. From the time they had escaped from the living-room this man had not been seen or thought of, but that he was a part of the mystery there could be no doubt. It flashed over Miss Cornelia that, although he could not possibly have locked them in, in the darkness that followed he could easily have fastened the bat to the door. For the first time it occurred to her that the archcriminal might not be working alone, and that the entrance of the Unknown might have been a carefully devised ruse to draw them all together and hold them there.
Nor was Beresford"s arrival with the statement that the Unknown was moving through the house below particularly comforting.
"He may be dazed, or he may not," he said. "Personally, this is not a time to trust anybody."
Beresford knew nothing of what had just occurred, and now seeing Bailey he favored him with an ugly glance.
"In the absence of Anderson, Bailey," he added, "I don"t propose to trust you too far. I"m making it my business from now on to see that you don"t try to get away. Get that?"
But Bailey heard him without particular resentment.
"All right," he said. "But I"ll tell you this. Anderson is here and has arrested the Doctor. Keep your eye on me, if you think it"s your duty, but don"t talk to me as if I were a criminal. You don"t know that yet."
"The Doctor!" Beresford gasped.
But Miss Cornelia"s keen ears had heard a sound outside and her eyes were focused on the door.
"That doork.n.o.b is moving," she said in a hushed voice.
Beresford moved to the door and jerked it violently open.
The butler, Billy, almost pitched into the room.
CHAPTER EIGHTEEN
THE BAT STILL FLIES
He stepped back in the doorway, looked out, then turned to them again.
"I come in, please?" he said pathetically, his hands quivering. "I not like to stay in dark."
Miss Cornelia took pity on him.
"Come in, Billy, of course. What is it? Anything the matter?"
Billy glanced about nervously.
"Man with sore head."
"What about him?"
"Act very strange." Again Billy"s slim hands trembled.
Beresford broke in. "The man who fell into the room downstairs?"
Billy nodded.
"Yes. On second floor, walking around."
Beresford smiled, a bit smugly.
"I told you!" he said to Miss Cornelia. "I didn"t think he was as dazed as he pretended to be."
Miss Cornelia, too, had been pondering the problem of the Unknown. She reached a swift decision. If he were what he pretended to be--a dazed wanderer, he could do them no harm. If he were not--a little strategy properly employed might unravel the whole mystery.
"Bring him up here, Billy," she said, turning to the butler.
Billy started to obey. But the darkness of the corridor seemed to appall him anew the moment he took a step toward it.
"You give candle, please?" he asked with a pleading expression. "Don"t like dark."
Miss Cornelia handed him one of the two precious candles. Then his present terror reminded her of that one other occasion when she had seen him lose completely his stoic Oriental calm.
"Billy," she queried, "what did you see when you came running down the stairs before we were locked in, down below?"
The candle shook like a reed in Billy"s grasp.
"Nothing!" he gasped with obvious untruth, though it did not seem so much as if he wished to conceal what he had seen as that he was trying to convince himself he had seen nothing.
