So my BRB has an event definition for this. I don't think that carries into the plural, these. The event, I think, is referring to making a statement such as "this is exciting". This is hard to extend to a statement about multiple events. The home counties part is a given, so I guess Kruger thought an obscure definition with an improbable pluralisation was needed to throw us off the scent! Enjoyable puzzle overall though.
