Simon and Matt are joined in the studio by multi-million selling author, Lisa Jewell.

They discuss why her new novel, 'None Of This Is True', was the quickest book she has ever written, and how she leaves her readers guessing until the very end.

They also talk a little about her process, how the book was influenced by an academic and author who followed Lisa's writing journey for a year - and - why she prefers instant coffee to something, well, decent.
