Book excerpt: 'An assured debut that unashamedly harks back to classic thrillers... reads like a knowing blend of John Buchan's The 39 Steps and Robert Louis Stevenson's Treasure Island.' - The Irish Times A ship adrift, all hands dead. A lighthouse keeper murdered in the night. The Crown needs a man to find the truth. Doctor Mungo Lyon, his reputation tarnished by the Burke & Hare scandal, and forbidden to practise as a surgeon, is the wrong man. That's exactly why the Crown chose him.
