Contents header returns after first chapter

Question

I am using \documentclass{book} and tocloft for the table of contents.

The way my document is structured I have the table of contents, then a \chapter*, then part one, chapters, etc.

For some reason, the "CONTENTS" header is on the blank page after the \chapter* finishes. If I change that chapter to \chapter{Prologue} instead of \chapter*{Prologue}, it's fine (but I don't want that chapter numbered).

Any idea what's going on here or how to make it

\clearpage

\setlength\cftparskip{-2pt}
\setlength\cftbeforesecskip{1pt}
\setlength\cftaftertoctitleskip{18pt}
\tableofcontents

\clearpage
% fixme: ``Contents'' still shows up on the header after prologue

\chapter*{Prologue}
\addcontentsline{toc}{chapter}{\protect\numberline{}Prologue}
% Prologue goes here

\clearpage

\part*{Part One}
% and so on...

Answer 1

User \markboth to set the header entry for a starred, unnumbered chapter, such as

\chapter*{Prologue}
\markboth{Prologue}{Prologue}

You also could apply your header formatting here, such as \MakeUppercase{Prologue} if required. Also, if you use the title "Prologue" very often now, it could be a good idea to make a macro for that name.
