by Isaac Asimov, 1952
Really good! Magnifico, the clown, is the Mule! Defeats the Foundation by his ability to control men’s emotions. Almost gets Mis to discover the location of the 2nd Foundation but Bayta figures it out that the Clown is the Mule and kills Mis before he can tell. Mule loves Bayta because she truly liked him all on her own. She and Toran, her husband, were his friends – the Mule never controlled her (Bayta’s) emotions. He doesn’t kill them in the end.
