It actually wasn’t an entire book titled “The Perils of Pus Infection” it was only chapter two. I thought with that bit of information I could Google it and find out what the exact book was but I had no such luck. At first I was wondering if it was a medical book or a novel because “peril” seemed like a very dramatic word to be using for a medical book. Though textbooks sometimes like to liven things up a bit so I’m guessing it was a medical book.
