Robert Browning

This book is meant to be a companion to “Heretics,” and to put the positive side in addition to the negative. Many critics complained of the book called “Heretics” because it merely criticised current philosophies without offering any alternative philosophy. This book is an attempt to answer the challenge. It is unavoidably affirmative and therefore unavoidably autobiographical. The writer has been driven back upon somewhat the same difficulty as that which beset Newman in writing his Apologia; he has been forced to be egotistical only in order to be sincere. While everything else may be different the motive in both cases is the same. It is the purpose of the writer to attempt an explanation, not of whether the Christian Faith can be believed, but of how he personally has come to believe it. The book is therefore arranged upon the positive principle of a riddle and its answer. It deals first with all the writer’s own solitary and sincere speculations and then with all the startling style in which they were all suddenly satisfied by the Christian Theology. The writer regards it as amounting to a convincing creed. But if it is not that it is at least a repeated and surprising coincidence.

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-writing.

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.
