Something Wrong
Perhaps she was so excited about her find that she didn’t really inspect the bag much. However, when she got home, she had a strange feeling that something was amiss with her treasured find — and, indeed, there was something off.
As she was cleaning it, she noticed that it was heavier than what it should be. She shook it and noticed that there was something hidden inside. She looked for a possible opening inside the compartment to see if she could fish it out — carefully, as you never really know what you might see from something you just got from a donations shop.
