"A wacky, nightmarish, deliriously well-written adventure story. It's hard to think of a more thrilling book." -Time Magazine
"The Man Who Was Thursday is not quite a political bad dream, nor a metaphysical thriller, nor a cosmic joke in the form of a spy novel, but it has something of all three . . . it remains the most thrilling book I have ever read." -Kingsley Amis
"Chesterton's tour de force is a thriller that is best read slowly, so as to savor his highly anarchic take on anarchy." -Kerry Fried
"A novel that fundamentally believes in the decency and the wisdom of us all, and you don't find too many of those." -Nick Hornby
"It's a damn good read that I believe should be read by everyone in politics." -Terry Pratchett
"Chesterton's great book gives me food, armor, and a compass for the soul." -Anne Perry
"A raucous carnival of genres: thriller, farce, detective story, dystopia, fairy tale and gothic romance. It can be read as a philosophical treatise or a fraught expression of religious conviction but above all it is gloriously entertaining." -Simon Hammond, The Guardian
"A myth both richly comic and nightmarish, and the scene at the end, where you discover at last who Sunday really is, is a theophany second in power only to the last four chapters of the Book of Job." -Frederick Buechner
