'If you are what you eat,' you reflect as the pigeon swoops down claim its prize, 'then pigeons must be 99% garbage.' To your astonishment, the pigeon has a note tied to its foot which seems to be addressed to you. It reads : "The presence of yonder castle whack requests yeast for dessert. Incidentally no poodle burgers. They've gone to Fulham." Will you interrogate the pigeon to find out what this means, or ask the pigeon its name?
