Book Description

A cunning serial killer, eluding capture at every turn, methodically executes their crimes using the alphabet as their guide. As a macabre calling card, the murderer leaves behind an ABC railway timetable beside each victim's lifeless body, with the open page indicating the location of the next killing. It begins with A: Andover, followed by B: Bexhill-on-Sea, and then Sir Clarke's murder is discovered at C: Chesston's seaside path.

It seems the perpetrator of these heinous acts is destined to remain at large, until a fatal error is made—one that challenges Hercule Poirot himself. As the fourth letter arrives, boldly challenging Poirot with their next target being Doncaster, media frenzy ensues and Scotland Yard mobilizes a significant force to prevent further bloodshed.

The killer's brazen challenge ignites a race against time, as Poirot and his team meticulously analyze each clue in their pursuit of justice. With the stakes higher than ever, the battle of wits between detective and murderer reaches its climax amidst the fog-draped streets of Doncaster, where the truth will finally be unveiled.
