After narrowly surviving the battle in the skies above Newearth, Major Ivor Hooke reluctantly returns to London for a court martial hearing with the Duke of Wellington. Intent on putting his adventures among the stars behind him, a chance encounter sees quite the opposite happening. From the filth-strewn slums of Victorian London to the great plains of colonial Mercury, Ivor will encounter new foes, old allies and one or two people who could be classed as either as he slowly unravels one of the greatest conspiracies the Solar System has ever known. One of Life's Great Mysteries is the second book in The Newearth Trilogy, and a follow up to 2017's A Curiosity of The Solar System.
