WILD, MAD, HILARIOUS AND
PROFOUNDLY MOVING TALE
It is very difficult to classify THE MAN WHO WAS THURSDAY. It
is possible to say that it is a gripping adventure story of murderous
criminals and brilliant policemen; but it was to be expected that the author
of the Father Brown stories should tell a detective story like no-one else.
On this level, therefore, THE MAN WHO WAS THURSDAY succeeds
superbly; if nothing else, it is a magnificent tour-de-force of suspense-
However, the reader will soon discover that it is much more than that.
Carried along on the boisterous rush of the narrative by Chesterton's
wonderful high-spirited style, he will soon see that he is being carried into
much deeper waters than he had planned on; and the totally unforeseeable
denouement will prove for the modern reader, as it has for thousands of
others since 1908 when the book was first published, an inevitable and
moving experience, as the investigators finally discover who Sunday is.
