To my great relief, The Murder on the Blue Train
features a third-person omnipresent style. Captain Hastings is only mentioned in this novel once. Instead, Poirot has a part-time sidekick in the very practical Katherine Grey. The have such an easy relationship from the get-go that I was hoping she'd become Hercule Poirot's love interest, even though she is several years his junior. Am I the only one who'd like to see Poirot in a relationship?
