Line Spacing in Page

Hello-

I am trying to adjust (lessen) the space between the lines of text in my Page body content. I am using the Radcliffe Theme, and here is the link to my Page: http://anescapetoholdonto.com/poems/the-lighthouse/

Any chance someone could help me get the CSS code for this theme to adjust the space between lines? Right now, the lines are seemingly double spaced, but I’d like them to be single.

Thanks!
