The leitmotiv of The Quincunx is the interplay of Chance and Design – do we perceive Design in our lives, or merely impose it? – underscored by the recurrence of those Dickensian coincidences that Dickens’s detractors so often deride as ‘contrived’, yet which occur in real life every day, but the foundational theme is greed: how it twists, degrades and ultimately destroys everything it touches, even the innocent, and how it so clouds the minds of men that they come to see their most heinous acts through an indestructible rose-coloured glass of self-justification. Like so much of Dickens, it is a cautionary tale.
