Lately I’ve been rereading Agatha Christie’s series
featuring Tommy & Tuppence.
Christie always did have a way with an easily readable & yet still
interesting mystery and these books are no exception. The series begins shortly after WWI in The Secret Adversary. Here we find Tommy & Tuppence looking
for mislaid papers of state that are vital to England’s future. We then move forward in time 6 years to find
the couple married and running a detective agency as a front for certain
espionage activities in Partners in Crime.
In N or M? we find them at the beginning of WWII seeking to thwart plans
by German sympathizers. The final two books
are By the Pricking of My Thumbs and Postern of Fate, both set well after WWII.
