An assured debut that unashamedly harks back to classic thrillers... reads like a knowing blend of James Buchan's The 39 Steps and Robert Louis Stevenson's Treasure Island. -- Declan Burke * The Irish Times * The story is fast paced and gripping... An adrenaline-filled adventure. * Scottish Field * A classic, colourful and fascinating adventure story... brilliantly told with plenty of derring-do. * Crime Review * This highly entertaining debut sits well in a long tradition of Scottish adventure novels and is a perfect winter evening read for fans of intrigue, daring do and jeopardy. * NB Magazine * The perfect dark and moody tale to keep you going this autumn... Immensely entertaining and as gripping as you'd hope from a crime novel, I look forward to more Mungo Lyon adventures. * CommonSpace * A beautifully crafted novel... written with a great eye to detail and its pace, storyline and ending all reward the reader. There is definite mileage in Mungo Lyon returning for future missions, though The Crown Agent stands as an excellent novel in its own right. * Undiscovered Scotland * A rollicking tale that grips the reader from beginning to end and is one I'd heartily recommend. -- Willie McIntyre * Scottish Legal News * It's got murder, smuggling, lighthouses and half of Burke & Hare. I bloody loved it!!! -- Lesley Kelly A story filled with murders, cryptic messages, a history lesson, slavery, a thrilling chase... A compelling read and an author to watch out for. * Lost in the Land of Books blog * An energetic historical spy adventure that's quite a ride, full of peril, menace and pursuit! Recommended. * Books.Tea.and.Me blog * This is a colourful and fascinating story - the first of what I hope will be many adventures penned by the talented Mr O'Rourke. * Alexander McCall Smith * Fast-paced and not a word wasted, this is a classic adventure that calls to mind Stevenson and Buchan. * S.G. MacLean *
