Witty, wonderfully written and endlessly surprising, The Man who was Thursday is a novel which defies categories. It is hard to believe it was first published a whole century ago and that its protagonists scamper about in tails and top hats 'like black chimney pots'. On one level, it is a breathless thriller worthy of 007 - featuring a descent into an international terrorist organization headquarters, a baffling game of subterfuge between spies and a high speed chase through central London after an elephant and a hot air balloon. On another, it is a profound meditation on the nature of identity and the theological problem of evil. Entertainment and such weighty themes make strange bedfellows indeed, but here it is as if they tear off the sheets and indulge in a 100-page pillow fight so much fun is had by their combination. Chesterton acts as a winking master of revels throughout, orchestrating the chaos in his inimitable style while scattering bon mots and charming comparisons with abandon. One of my personal all time favourites, 'the wild joy of being Thursday' is an experience I will return to again and again.
