背景：paul把zack送进精神病院，susan问及zack的下落时，paul骗她说zack送亲戚家了，并讽刺她问这么多，太八卦。
Mary Alice ::"Susan was infuriated by Paul's evasive answers."
"She was convinced he was deliberately hiding Zach, and hiding the truth.
She hoped that finding one would lead to the other.
To succeed, Susan would have to be evasive herself."


tending or seeking to evade; not straightforward; tricky; equivocal
hard to catch, grasp, etc.; elusive
这里应该取 难以捉摸的意思 不让别人知道你的真实意图
后面有讲到
susan 去邻居家里 想借小车跟踪paul，但是她没有直接说借小车，她先让邻居还她去年圣诞借的两个蛋，然后再转到借小车这个话题上，结果她借到了

太感谢了，请问第一句Susan was infuriated by Paul's evasive answers中的evasive是含糊其辞的意思吧，我在金山词霸上只查出了这几个意思，请问亲，您从哪查来的，有那么多的英文解释，很详尽啊，谢谢

英文解释是 英英在线词典里面的

好的，谢谢您啦
