The Verinder family’s goofy family doctor, whose social tactlessness gets him into an argument with Franklin Blake at Rachel Verinder’s birthday dinner. (Although he does not reveal this until late in the book, Candy secretly drugs Franklin with laudanum as a practical joke to get his revenge.) On his way home from the dinner, he falls sick due to the heavy rain, and his illness—while cured by his brilliant assistant Ezra Jennings—ultimately debilitates him. When Franklin visits Mr. Candy again at the end of the book, the doctor is withered and sickly, unable to remember what he means to say or hold a coherent conversation. However, the letter he writes notifying the Verinders and reader of Ezra Jennings, which forms one of the book’s final narratives, is completely coherent. This appears to prove Ezra Jennings’s theory: Candy can think coherent thoughts, just not express them.
