Mrs. Lovett didn't know what she had been thinking.
Well actually, she did know what she had been thinking.
She'd thought that maybe, when Sweeney Todd saw her wearing the necklace, he would think she was beautiful. He would fall madly in love with her and they would be united forever.
It had been a silly idea. No, a ridiculous idea. Something only a child would think was possible.
As she sat in the pie shop, cleaning her already spotless counter, Mrs. Lovett thought about the necklace. He hadn't told her anything about it, but she thought it might have something to do with Lucy.
He only reacted as angrily as he had just then when the situation was related to Lucy.
"Maybe it was her necklace," she muttered, talking to herself again. That seemed plausible. But why had the necklace been where it was?
Why had the necklace been where it was? The question was driving Sweeney Todd crazy—or, more crazy than he already was.
He kept turning the scene over and over in his mind. Lucy's face when she had received the necklace.
She had been happy. Her face had been one of bliss.
She hadn't been pretending.
A slight grin crept over his face as he imagined her smile. The grin lingered even when the image of Lucy smiling faded to an image of Mrs. Lovett smiling.
Earlier that day, Mrs. Lovett had looked so happy—he realized now it was probably because she had been wearing the necklace. A slight twinge of guilt muddled his thoughts as he pictured her face falling when he took it away from her.
No, no, no, he thought. Don't think about her. What's important is figuring out what happened to the necklace that allowed Mrs. Lovett to get a hold of it in the first place.
There she was, invading his thoughts again. He shook his head to clear his mind. What's important is figuring out what caused Lucy to let go of the necklace, he thought. Mrs. Lovett is unimportant in this matter.
It bothered him that Lucy had taken off the necklace. The fact that Mrs. Lovett had been wearing it was a minor concern.
Lucy had worn it all through their marriage. The last time he'd seen her, before he was shipped off, she had definitely been wearing it. He remembered it vividly.
Had she cast it aside, ashamed of the husband who had given it to her? He could think of no other explanation for its location other than that.
Maybe it was a coincidence. He liked to think of it that way, for he didn't want his memory of Lucy to be tainted.
But if Lucy had indeed thrown the necklace away, then he didn't want it. It would be a constant reminder of her betrayal.
But what could he do with it?
