The Secret Political Adviser

Just who is the secret political adviser calling himself The Man in the Room Next Door? No one knows. We don't even know his name.
But now the lid is about to be blown clean off, because the secret files of the world's most influential* political media adviser are published in this book. Packed with letters, memos, texts, tweets, emails, journal entries, leaked documents, and crude doodles, these pages will reveal who The Man in the Room Next Door is, and, more importantly, his thoughts on those who employ his services, including Donald 'dangerous puffin' Trump, Boris 'posh motorboat' Johnson, and some of their least competent colleagues.
The Secret Political Adviser is the evidence that anyone can be a world leader. Just as long as they're wearing the right earpiece.
