“This novel features Bright Young Things Between the Wars, a favourite genre of mine. Lady Lupin is a wonderful character, a brainless blonde and London socialite who marries a vicar twice her age. Theirs is a genuine love match, but "Loops" is hopeless as a vicar's wife. She drinks, smokes, receives visitors in her dressing gown until around noon, and is determined to have few if any babies. The vicar thinks she's adorable and couldn't care less. What "Loops" does have is a memory like a steel trap and a habit of retaining and blurting out small details that have escaped everybody else's notice, which is enough evidence for the vicar's nephew in His Majesty's Secret Service to piece together and solve the mystery of who poisoned the curate.”
