+;% File : PUZ001+1 : TPTP v5.4.0. Released v2.0.0.
+;% Domain : Puzzles
+;% Problem : Dreadbury Mansion
+;% Version : Especial.
+;% Theorem formulation : Reduced > Complete.
+;% English : Someone who lives in Dreadbury Mansion killed Aunt Agatha.
+;% Agatha, the butler, and Charles live in Dreadbury Mansion,
+;% and are the only people who live therein. A killer always
+;% hates his victim, and is never richer than his victim.
+;% Charles hates no one that Aunt Agatha hates. Agatha hates
+;% everyone except the butler. The butler hates everyone not
+;% richer than Aunt Agatha. The butler hates everyone Aunt
+;% Agatha hates. No one hates everyone. Agatha is not the
+;% butler. Therefore : Agatha killed herself.
