"We'll go some other day, and take two candles and a box of matches with us," she announced.

"Is it really any good?"

Cicely's spirit quailed at the prospect of once more encountering the unknown horrors that might be lurking in that dark attic. She could not forget the groans she had heard there.

"Of course it is! I didn't think you'd be the one to draw back," said Lindsay reproachfully. "We've both pledged ourselves to do everything in our power to help Monica. It would be mean and cowardly to give in just because we felt afraid. If you don't care to come with me, I shall have to go alone. I'm only waiting for a good opportunity."

For several days the opportunity tarried. Mrs. Wilson was too often about the passages to make the expedition safe. On one occasion Cicely went to act scout, but found the housemaid sweeping the top landing, and had to beat a hasty retreat.

They were not able to discover where Lindsay's leg had descended so suddenly through the rotten floor, or whether any of the ceilings in the upper rooms had suffered in consequence. If Mrs. Wilson had found out the damage, she kept her own counsel. When at last they managed to seize a favourable chance, and to steal up the winding staircase, a sad checkmate awaited them. The door of the lantern room was securely fastened with a padlock.

"Scott said he was going to put one on," said Lindsay, after staring blankly at the unwelcome impediment. "Don't you remember, when he was talking to 'The Griffin' in the picture gallery, and she told him we had been here?"

"I'm certain they suspect us," returned Cicely. "Perhaps they only took part of the silver or jewellery away in that sack, and the rest is still up in the garret."

The sole plan of action they could think of after this last disappointment was to keep a watch upon Scott. If he had really concealed a portion of the treasure in the garden, he would probably go to look at it occasionally, to make sure of its safety. At Cicely's urgent request they had already made a careful examination, with a trowel, of the bank where Scott had been digging when they surprised him in the dark. It was fruitless work, however; nothing was there.

"I told you beforehand they wouldn't be so foolish," said Lindsay.
