In this sentence:
She did not want to meet Lettuce. That was a rare feeling for her; she would usually never avoid anybody, but Lettuce was somehow different. Was it just dislike, or was it something different - a wariness born of the knowledge that he did not like her and would be perfectly happy to harm her interests - such as they were?
What does "such as they were" mean? What does "they" refer to, "her interests", then why using the dashes?
Thanks!
