In The Fabric of Sin, the ninth outing for Britain's most original crime fiction heroine, Merrily Watkins is investigating the ancient connections between The Master House, close to the Welsh border, and the nearby church, built by the Knights Templar. A sudden death leads her back to Garway, to uncover fibres of fear and hatred stitched into history and now insidiously twisted in the corridors, and the cloisters, of power.
