The daylight revealed its extraordinary condition with great clearness; the dust, dirt, and cobwebs looked forlorn in the extreme. On a hook on the door, which presumably led into the Dower House landing, hung a net filled with hard wooden balls, and as the draught blew in from the opening over the fireplace, these swayed about and knocked with a gentle rapping against the panel.

"There's your ghost, Dulcie," said Deirdre. "That was the tap-tapping you heard in the passage. It wasn't a spook after all, you see."

"You were just as scared as I was," protested Dulcie. "I think I'm rather scared now. Let's go! Suppose whoever's been here making tea were to come back? I believe I'd have hysterics."

There was something in Dulcie's suggestion. It had not before occurred to Deirdre that it would be unpleasant if the owner of the kettle were to return and demand an explanation of their presence.

"We must put the shutters back," she decreed.

This was easier said than done, but after considerable trouble they managed to restore the room once more to its former state of darkness. Their candle was burning rather low, but they hoped it would be sufficient to light them to the mouth of the cave. With the aid of a chair they climbed on to the mantelpiece, passed through the door in the panelling to the vaulted chamber, and on into the subterranean passage. They scurried along as fast as they could without stumbling, partly from fear that the candle would go out, and partly in dread lest somebody should be coming from the entrance, and meet them on the way. It was with a feeling of intense relief that, bearing the last guttering scrap of candle, they at length emerged into the daylight.

"Here we are, safe and sound, and met no bogy, thank goodness!" rejoiced Dulcie.

"There's our bogy, waiting!" said Deirdre, pointing to a school hat which suddenly made its appearance from below.

"Gerda, by all that's wonderful!" gasped Dulcie.

Yes, it was Gerda who had followed them, and who now watched them as they came out of the cave. She was paler than usual, and there was a queer set look about her mouth.
