Russell, R B - The Woman Who Fell To Earth

The woman would be Catherine, who fell to her death on Tanya’s roof. Once friends, they had cooled after Catherine wed Tanya’s favorite uncle, and began appropriating.
Is there a police investigation of just how Catherine fell, apparently, from open sky? Alas.
Catherine was the champion of an esoteric horror writer cum hack. After his death, she had jealously guarded his papers, as well as the sixtystone *.
Tensions notwithstanding, Catherine’s will made Tanya the executrix of everything. Almost immediately, interlopers appear: rivals, cheats, liars, poseurs, thieves.
All simmering the narrative. Until – midway – an unexpected individual arrives.
The plot becomes haphazard, loose, improvised, bordering on what I call fantasy island.
I will guess the author was being playful, lightening the tone, although I found it awkward.
I read to the conclusion, hoping, hoping, yet the energy had drained and the tale sputtered out.

Sixtystone: an in-joke or knowing reference. To familiarize yourself, read Machen’s Three Imposters first; it’s a brief novel. If time pressed, read the story “The Novel Of The Black Seal.”
