The End of the Line by Gillian Galbraith (Polygon, 2019)
Gillian Galbraith has been an advocate, a journalist, legal correspondent. Previous novels, following the investigations of her detectives Alice Rice and Father Vincent Ross, have won her many followers. Her new book introduces her new hero, Anthony Sparrow, an antiquarian book dealer who arrives in a suitably gloomy and wintry mansion to clear the house of books left by the recently deceased professor of medicine. But Sparrow uncovers letters, diaries and other documents which make his death increasingly suspicious.
