Scene: the Drones smoking room.
"I say, what climbed up Pongo Twistleton's pants leg? I was getting some lads together to go see the monkey house at the zoo, and he nearly bit my head off when I asked him!" inquired the Bean.
An Egg inquired, "He has been touchy lately. What exactly did you say to him?"
"Why, I asked him if he was up for a pleasant and instructive afternoon, and he turned on me and shot me a look that froze me to the marrow!"
"I can explain," said a nearby Crumpet. "Last week Pongo's Aunt Jane went to Baden-Baden to take the waters, and he had to play host to his Uncle Fred, a notoriously adventurous old git. The words 'pleasant and instructive afternoon' bring the horror of it back to life."
"What, Lord Ickenham? But he's such a pleasant geezer, how could he bring anything but joy?" said the Bean.
"Pongo told me all about it. It seems that he had Uncle Fred for 5 days in a row, Monday through Friday, and on each day he'd tag along after the old boy and find him posing as some new character, raising havoc in a different location each day. The old boy thinks big - he passed himself off as a police detective, a diplomat, a nerve doctor, an adagio dancer, and a judge, and he preferred very grandiose first names: Alphonse, Cornelius, Maximillian, Octavio, and Wilberforce. The last names he chose were fairly odd as well: Greenbuck, Philpot, O'Sullivan, Troutman, and Winkle. In any case, he wound up perpetrating these farces all over town, at Covent Garden, Regent Street, Hyde Park, Picadilly Circus, and down at Wembley - a new venue every day. Why, the whole week so upset poor Pongo, that he was unable to recall just who Uncle Fred pretended to be in which place, on what day. All that came to him were a dozen scraps of recovered memory from the trauma. Indeed, his own nerve doctor says it might help if he could reconstruct the events fully, in order to look them in the eye and diminish the impact. Until he does that, he may remain skittish as a rabbit."
Can you, with the 12 clues below, help Pongo recall what names Uncle Fred took, what he pretended to be, and where he did it, for the five days he was on the loose?
