Very generous review of The Poison Tide in January’s ‘History Today’ magazine. Jerome de Groot writes that ‘it is a cracking read, a thriller that has heft and a challenging and engaging protagonist…. a powerful and forthright book.’ And Allan Massie was good enough to make The Poison Tide one of his Christmas choices in ‘The Scotsman’: ‘every bit as good as its predecessor, ‘To Kill A Tsar’.
