Gahagan proposes after being suspected of having an affair with Lord Crome's wife in "Ring of Lovers". Joan, now married to Gahagan, appears in the framing sequence of "A Tall Story". Stories The Three Horsemen of the Apocalypse The paradox is introduced when a casual discussion turns to matters of European politics, and Pond recalls an episode during a war between the Prussians and the Polish. The fact, insists Pond, to Wotton's dismay, is that the Prussian soldiers were too obedient. Marshal Von Grock failed in his attempt to execute the influential Polish poet and singer Paul Petrowski because two of his soldiers did precisely what he asked. The whole thing went wrong because the discipline was too good.

After hearing the lawyer's story of what Gahagan said when leaving the Varney house, Pond introduces the paradox: Gahagan said exactly the same thing to all three witnesses, despite their conflicting reports. When Doctors Agree The paradox, simply put, is that two doctors once agreed so thoroughly that one naturally murdered the other. In the framing sequence mention is made of an agreement between the Poles and the Lithuanians about Wilno, and Pond mentions Tweedledum and Tweedledee (who agreed to have a battle) and tells the story of a protracted argument over morality which came to an abrupt conclusion. Pond the Pantaloon Pond introduces the paradox—that the pencil was relatively red, which was why it made such black marks—but Gahagan must go to Wotton for the explanation. Wotton tells the story of how Pond saved England and was shot at five times in a railway station waiting room, all because of the "pencil" which made the "black marks". The Unmentionable Man During a discussion of deportation, Pond mentions a man who was so well-regarded that officials longed to deport him
