Who Was Thursday is a surreal thriller set
in London at the turn of the century. Chesterton's spy fantasy
is considered by many to be his masterpiece.
The story's hero, Gabriel Syme, an undercover detective, infiltrates
a secret council of revolutionaries, named after the days of
the week. The group, led by the terrifying and grotesque 'Sunday',
is dedicated to the destruction of society. Syme, posing as an
anarchist, gets himself voted onto the council as the new 'Thursday'
and sets out to foil their evil plans and single handedly save
his world. On the perilous journey that follows, we encounter
farcical events, a twisting plot and a series of dramatic revelations
which crank up the tension as the true identities of the council
are revealed one-by-one.
