The ABC Murders by Agatha Christie

This week I am heading all over the country with Lorraine from Once Upon a Nightmare as we follow Hercule Poirot on one of his toughest early investigations, The ABC Murders. Not only does he have to contend with a serial killer who seemingly has no discernable MO, but he is up against the clock as this murderer is putting a timer on it all. Will he solve the case? Will he beat the killer at his own game? We will reveal some, but not all of this, this week in the usual Being Bookish spoiler-free fashion.
