You know what you're getting when you read Phyllis Whitney, old fashioned writing and a formula: Beautiful, wealthy young woman, married to an unsuitable man, attracted to another, strong, better man, and someone out to "get" her. Almost invariably she is on some level stupid.
Spindrift kept my attention with some decent writing and description of Newport. As a lifelong Rhode Islander, it was a treat to read of and recognize familiar spots: the mansions, Cliff Walk, Bellevue Avenue and Thames Street, Bowen and Banister wharves. The mystery here was nominally better than most and kept my interest until the ridiculous ending, so I raise my rating from 2 starts to three.
Why do I keep reading Whitney? I was a big fan in my youth and, as bad as it is, it's rather fun revisiting.
