The Arcanum battles demons in 1919

I am not familiar with Thomas Wheeler’s novel The Arcanum, but this description in Variety sounds at least a little interesting:

Gold Circle Films has picked up feature rights to Thomas Wheeler’s fantasy-adventure “The Arcanum” out of turnaround from Miramax.

“The Arcanum,” Wheeler’s debut novel, is set in 1919 and follows the titular secret society comprising the era’s leading occult investigators — Arthur Conan Doyle, Harry Houdini, H.P. Lovecraft and Marie Laveau — as they battle demons descending on New York City, including a serial killer of angels.

Hmmm. Set in 1919, you say? I am reminded that James A. Owen’s novel Here There Be Dragons — which imagines that fantasy writers J.R.R. Tolkien, C.S. Lewis and Charles Williams had some supernatural adventures of their own — takes place only a year or two before that. I can’t help wondering what might happen if these two groups were to meet — though I don’t suppose the worlds created by Wheeler and Owen are all that compatible.
