Breath of Suspicion by Elizabeth Ferrars was first published in 1972. The setting is London and later on Madeira.
Richard Hedon is in partnership with his brother, they own a bookshop which deals with rare books. Richard’s sister-in-law is always trying to pair him up with possible wives, she believes he has an aversion to commitment.
When Richard meets Hazel Clyro at a party he falls into a sort of relationship with her, she’s often stand-offish though. Her husband Paul had been a scientist and a few years previously he had just disappeared, so she didn’t know if he was alive or dead. One of Paul’s work colleagues had turned out to be a spy. Had he been kidnapped or murdered?
Richard decides to follow some clues which lead him to Madeira and danger.
This is an enjoyable read, it’s the sort that you can’t say too much about in a review though.
Elizabeth Ferrars is for some reason known as E.X. Ferrars in the US. She was born in Burma into a Scottish family and lived in Edinburgh in later life. So far I’ve enjoyed all of her books, not that I’ve read them all, she was quite prolific as you can see from her Fantastic Fiction page.
