Le nom de la carte Red Herring, déjà précédemment utilisé pour Red Herring (Mystery booster), fait référence à l'expression anglaise "red herring", qui désigne une fausse piste destinée à détourner l'attention dans une œuvre policière, au cinéma ou en littérature.

Source (Red Herring - "This card knew its task from day one. A murder mystery set needs to have red herrings (i.e., clues that seem to lead in the right direction but end up leading elsewhere), so how could we not have a card called Red Herring? Before I get into the card design, I'll discuss the elephant in the room. Magic, sort of, already has a card called Red Herring, one of the playtest cards from Mystery Booster. There's a rule that every card name in English must be unique, meaning that if there's a card called [Name], only one card called [Name] can exist. The playtest cards live in an odd area. [...] so the decision was made that they didn't take up a name slot. Future cards could use the name. That was great news for Red Herring and Pick Your Poison, which would both end up getting a card in Murders at Karlov Manor.")
