Doctor Who Vs. The ABC Murders

This thriller (another Agatha Christie Ltd. and Mammoth Screen collaboration) is
the latest adaptation from Sarah Phelps, and is based on The A.B.C. Murders, widely regarded as one of
Christie's best mysteries. Published in 1936, the form of the novel is notable for combining first-person and third-person narratives,
previously employed in
The Man in the Brown 
Suit. Captain Arthur Hastings acts as narrator
of the story, but Poirot's friend is absent from this new reworking.
Mike Holgate's book,
Stranger Than Fiction, claimed that the Queen of Crime was inspired by the infamous White-
chapel Murders of 1888.
The whodunit was first adapted in 1965 as The Alphabet Murders, followed
by LWT's version for the popular Poirot series (in 1992), then a BBC radio dramatisation in 2008.
Here, Hercules Poirot (now portrayed by Illinois-born actor John Malkovich) hunts ABC, a serial  killer who dispatches his victims in alphabetical order.
The period drama (shown over three consecutive nights from Boxing Day)  concluded on BBC1 last night and featured Rupert Grint (as Inspector
Crome), Andrew Buchan, Tara Fitzgerald, Gregor Fisher, and fourteen
