Beethoven's Assassins

'The overall effect is like a brilliantly well-informed 200-year history of philosophy, science, music and mysticism, touched with an edge of Da Vinci Code hocus pocus, in the sense of an alternative "sub rosa" world history never quite revealed. To say so, though, is to miss the sheer fun and narrative energy of Crumey's writing, the skill and insight with which he conjures up each of his narrators from the repellent to the poignant, and the huge ingenuity with which he interweaves their stories, including that of Adam Crouch, a failed writer and memorably seedy 21st century buffoon, who enters the story by accident, and becomes its final boozed-up witness to timeless tragedy.
There's something profoundly post-modern about the dense cultural references, and the complex patchwork of fact and fiction, that make up Crumey's narrative; and in that sense it continues in a vein he has been mining for the last 25 years and more. The intensity with which the story questions the very nature of time, though - and follows its central voice, Robert Coyle, through the strange reality-shifting nightmare of the pandemic - seems entirely of this moment; as if Crumey were leading us into a terminal vortex of history and thought, music and culture, parallel universes and competing realities, where all things sparkle and implode with extraordinary vividness, on the edge of oblivion.'
