Hoodwink

Yvonne and Steven visit a London hospital only to find themselves trapped inside the headquarters of an ancient Newtonian society.
Their escape with the Order's secret history sets them on a perilous adventure up the canals of England, pursued by the Order's remorseless Archbishop.
The best they can do for allies are a batty Marquis and his wife, ex-convicts and an unreliable demon.
They have a mystery to solve, but first they must survive.
