Outlander author Diana Gabaldon has signalled that she may go beyond book 10 in the time-travelling saga.
The creator of the historical drama also admitted that she kept the first instalment a secret from her husband.
The penultimate season of the show is underway and 71-year-old Gabaldon has previously said the book series will last for 10 instalments. She is currently working on the 'final' one.
