次の文章の解説、お願いいたします。
いま、英語の短編小説を読んでいるのですが、分からない文章があるのです。
"Ruby was Sally’s age. They had gone through school together,
but they had never been friends. In those days, Ruby had been
an outrageous flirt, the first in their year to appear in eye-shadow
and a smear of lipstick, and the leader in every other step towards
maturity. The boys had fought battles in the playground over her
and she had rewarded them with favours in the cycle shed that
were whispered about with sly smiles and sniggers."
この中の、最後の文章、
"she had rewarded them with favours in the cycle shed that
were whispered about with sly smiles and sniggers."
が、よく、分からないのです。
「ルビーは、勝者への褒美を、自転車小屋の中で、与えた。」
"in the cycle shed that were whispered about with sly smiles and sniggers"
が、いまいち、分からないのです。
どなたか、ご解説をよろしくお願いいたします。
