I confess I have not read any Darcy Coates, so cannot comment on the substance of this article. However, if haunted houses are your thing, may I humbly suggest some of my own gothic mystery novels? I think you'll like the protagonists in them too. Here are some links you can check out:
You would also probably enjoy Spectre of Springwell Forest and The Thistlewood Curse, both of which feature hauntings of a kind.
By pure coincidence, The Birds Began to Sing also features a "Blackwood House" but I can assure you that's where the comparisons will end.
