Well-paced and beautifully written. Rendell “hated” (her word) Agatha Christie, because Christie‘s characters are ordinary but turn suddenly turn violent. Rendell‘s own characters act in keeping with what would, in time, become established neuroses and behavior patterns. But this book is unquestionably dated. Modern readers will see the end of this coming far in advance; our ideas of “neurosis” have changed since 1964. Still highly enjoyable!
