The Lady in the Car with Glasses and a Gun
Bantam, New York, 1971
The blurb on the back:
Shooting someone to death from hundreds of miles away or driving so fast that you're back before you've left isn't possible ...
A woman regins consciousness in a public restroom and finds that she appears to be living someone else's life. The rest of the novel is an attempt to piece together a story that hovers between dream, paranoia and amnesia.
To be honest, it's not very good. Competent in a dull sort of way, but not something you'd recommend to a friend. So I'm not going to recommend it to you.
However, it's a nice-looking book because it comes adorned with stills from the 1970 movie which starred Samantha Eggar, Oliver Reed and John McEnery. They look like this:
ENTERTAINMENT VALUE: 1/5
HIPNESS QUOTIENT: 2/5
