There was a tapping at the door; a maid came in. She advanced towards the girl with something held out in her hand.
"Excuse me, Miss Forster, but is this yours?"
It was a locket, attached to a slender gold chain. The girl looked round quickly; she made as if to open the box she had just now shut. Then she said:
"I don't think it can be mine, but it resembles one I have; please let me look at it."
She took the locket and examined it closely. As she did so her face changed, as if something had startled her. She looked at the maid, with in her eyes what might almost have been a look of fear. Then, turning her back, as if to hide the agitation which she could not help but feel, she touched a spring; the locket came open. At the sight of what was within she broke into a sudden exclamation; she swung right round again. There was no doubt that something had startled her now; the blood had come into her cheeks, her eyes were wide open, she trembled.
"Where did you get this?" she cried.
"If you please, miss, I found it on the floor outside your room. I was coming along and I saw it lying there, and it was so close to your door that I thought you might have dropped it."
"When was this? When did you see it there?"
"A moment ago, miss; as soon as I had picked it up, I knocked at your door."
"But it's inconceivable, incredible! It certainly wasn't there just now when Lady Cantyre went out."
