Night Frost

So I gave up reading Return from the Stars because I could remember it too clearly although I must have read it about 10 years ago. However, I can't remember what happens in the main plot in Night Frost (another Inspector Frost book), although I do remember some of the incidental scenes, and I read this less than 3 years ago. Perhaps that's because the plot is always pretty much the same: missing children, murdered prostitutes, body discovered after many years, police out searching in freezing cold weather and Frost battling it out with Mullet over internal bureacracy and form-filling.
