American owner of a failing gallery, Toni, is unexpectedly called to England when she inherits a manor house in Hertfordshire from a mysterious lost relative. What she really needs is something valuable to sell, so she can save her business. But, leaving the New Mexico desert behind, all she finds is a crumbling building, overgrown gardens, and a wealth of historical paperwork that needs cataloguing. Soon she is immersed in the history of the house, and all the people who tended the gardens over the centuries: the gardens that seem to change in the twilight; the ghost of a fighter plane from World War Two; the figures she sees in the corner of her eye. A beautiful testament to the power of memory and space, Threading the Labyrinth tells the stories of those who loved this garden across the centuries, and how those lives still touch us today.
