The Shadow on Mockways

Henry Beale wants to paint Mockways, an ancient country house that sits in isolation on the Welsh border. When the artist's friend Edward Falkland saves the life of Mockways' owner, the eccentric millionaire Jessamy Dobree, and is offered a favour in return, he asks for access to the house on Beale's behalf. But Dobree flatly refuses Falkland's request... until he mentions the name 'Sarah Lomax'. Before he knows it, Falkland is whisked off to the strange old property-along with the rich man's ward, Isabel Conway, and her nurse-and held there against his will, forced to take part in ghost hunts while Dobree and his sinister companion, Harvey Manning, search the house from top to bottom, looking for a mysterious box hidden long ago by Mockways' previous owner.

'A thriller that is mysterious in the manner of Le Fanu.' - Daily News, 21 June 1932.

'Contains all the elements of a real thriller, and is saturated with the atmosphere of a terrifying house where weird things happen.' - The Bookman, June 1932.

The New edition published by Nezu Press in 2025 includes a 19-page biographical essay by Gina R. Collia: 'Margaret Campbell: The Lady with the Hundred Names'.
