They reached the side entrance without hearing any footsteps behind them. If Scott had tried to follow them, they had evidently managed to elude him, and he must have given up the chase. The door was still unbolted, and they hurried breathlessly upstairs, luckily meeting nobody on the way. What a harbour of refuge it seemed to be, back in their own room! Without daring to light the candle, they went back to bed again with all possible speed.

"Well, we have had an adventure!" began Lindsay, when they were once more comfortably ensconced between the sheets.

"Do you think Scott noticed who we were?" whispered Cicely.

"I can't tell. He had just time to catch a glimpse of our faces before the lantern went out."

"I'm sure they were doing something dreadful that they wanted to keep secret, he looked so utterly horror-stricken at seeing us."

"There's no doubt about it. The unfortunate part is that now they find they've been discovered, they'll bury the treasure somewhere else instead."

"What a pity we fell just at that moment!"

Cicely's voice was very doleful.

"It will have aroused their suspicions, too, and will make them extra careful," lamented Lindsay. "If Scott recognized us, he and Mrs. Wilson will know we're watching them. They'll owe us a grudge. 'The Griffin' was bad enough before, but she'll be worse than ever now."

They scanned the old housekeeper's face narrowly next morning, as she carried the coffee into the dining-room, but her countenance wore its accustomed aspect of grim inscrutability. If she connected them with last night's happenings, she certainly did not betray the knowledge; it was impossible to tell whether she mistrusted them or not, or what feelings lay concealed under her forbidding exterior.
