‘The Invisible Boarder’ by Mildred Davis, Random House, 1974
The Invisible Boarder by Mildred Davis, an American writer, was published in 1974 but harks back to the Fifties in style or even earlier. The plot is very simple but none the worse for that: a guilt-ridden woman returns incognito to the small town where four years ago her small son was murdered.
This novel has a large dose of gothic in it: spooky house, seemingly disturbed landlady, and repeatedly imperilled heroine who needs to be rescued by others, including the inevitable love interest. But it is entertaining and suspenseful despite the rather tired formula.
