Guthrie Featherstone could fill a whole page. Highlights include frantically trying to lose a golf match against an influential judge in an early series, inadvertently invoking the wrath of feminist groups in "Rumpole and the Tap End" (and his later, equally disastrous attempts to extricate himself), and being tricked by Rumpole into inadvertently threatening a judge's strike in "Rumpole and the Summer of Discontent."
