"Report" is the subject and the rest is describing the report.
In "The Most Dangerous Game," we meet Zaroff and Rainsford. Rainsford is a hunter who is travelling to the Amazon in order to hunt a jaguar. However, he falls overboard and ends up in a semi-deserted island, where Zaroff lives. Zaroff is also a hunter, but he informs Rainsford that he prefers to hunt humans, as they are a lot more interesting. He tells Rainsford that if he is able to avoid being hunted for three days, he will regain his liberty. Although Rainsford does so, and Zaroff accepts not to hunt him anymore, the story implies that Rainsford ends up killing Zaroff and winning the "game."

It was believed that a lady should manage her servants, prepare parties and support her husband but not a spy and this worked in Van Lew's favor.
